sir can i ask! is it safe to use 50v 10,000uf(m) capacitors and connect to the motorcycle battery!?
I charged 40 v condensor with 16 v and canected it to fan (power suply +to - of condensor ) -of condencor to fan +it.
It spined 1 s longer because using pc cgarger (16v) it spins 3s because of cpndensors in apple pc charger . It works (charger ) because it has come kind auto fuse in it because it was shortcirkut aloot of times (specely then when i made plasma with pencil grafite )
@@Basher189 motorcicle needs only 12v if ypu use 50 v ypu might make buge mess with elecronic ( burn fuses ) and that is hard to aces some beter use 12- 15v condensor
Now do a video on aircraft fuel probes.
@@memesaregreat8815 NO!
Using a "12V" rated capacitor may be unreliable, even dangerous!
The "50V" printed on a capacitor is the max voltage rating. Please use capacitors with max ratings higher than battery voltage (the higher the better) , so it will live longer and survive power spikes and inductive surges. This technique is called "derating", and it will prevent some failure modes.
Always read and understand the specs of the component you are using, and what the markings on the component actually mean.
i love it when youtube decides to recommend high quality educational video from a channel im not subscribed for
Same
For real...😁😁😁😁
So much of Coincidences
For me toooooo
Yes exactly.. never heard of this youtuber.. but since youtube recommended it, and i enjoyed how informative this was, imma subscribe
Explanations like these put to shame the traditional college textbooks and classes.
School dont teach online learn more
Ive been studying this for 1yr and yet a simple 8:41 min video explained a lot more.
Ehh... I don't know about that. Sure there are videos online that often have incredibly intuitive and good explanations for some concepts like 3Blue1Brown with his calculus series for example.
But videos rarely go deep into topics at hand, so you always need to research using material often found in books anyways.
And this video is not a good example ( Not that the video is bad, I liked it ), like legit, this is stuff you find in ANY textbook for electronics. We're talking like.. the first pages ( of chapters dealing with caps obv ).
Online is better than offline learning. I have understood much more than in class. Ok plzz dont interrupt
Juan Carlos Patiño Peralta Colleges only teach liberalism and perversion. No thank you.
I am an Electrical Engineer and I wish that this explanation is provided to the engineering students before all the theory and math in order to have a practical understanding of this device. Keep up the good work! Excellent!
I played one on TV.
@@jimnicosia5934 If a capacitor can only store DC voltage how do they operate with AC current flowing in them sir?
@@jerrodwilliams6789 I think you need to filter the ac with diodes first to turn it to DC
I fully agree! I had such a hard time wrapping my head around the theory when I didn’t even know what use the component had! 😭
I’m starting my electrotechnical level 2 in septmember is it fair to assume a capacitor is involved a lot in this course. Asking you because you have completed college sir.
I'm gonna cry at how good you are at explaining things man. This is seriously one of the best educational channels on CZcams.
thats funny 'cause i got that feeling a few days ago with another guide.
some people are just so much better than others when it comes to explaining and demonstrating stuff that it moves me.

you pay all this crazy tuition to a college, but don't understand shit. you come in here for free and get all the knowledge. this is life.
College is scam. You pay money for wasting your time and listening political bs.
@@ozmobozo I agree. most college are scam. ppl with high school degrees are making millions of dollars a year. graduate College students are in debt and unemployed.
@@shonty4986 *you. Also non-native English speakers exists. You can't expect everyone to be a Shakespeare especially if you yourself are too lazy to put three letters together.
@@shonty4986 you're making fun of me because I misspelled a word?
The only issue is you can study and gain all the knowledge in the world that you need to know about capacitors or Electrical Engineering, however no one will hire you because there's nothing to show for it.... Unless you have a degree no one seems to give a sh*t that you may even know more than they do. I hate college, or school for that matter. Everything that I have learned has been by me or by just watching someone do something. I do agree that extremely specialized fields like brain surgery require schooling, but somethings just do not.
I graduated from Electronics in college in the 80s and you do a much better job at explaining a capacitor in a short video than what I learned in 2 years of college. Great video....I subscribed and gave you a like...keep up the good work and I look forward to viewing all your videos.
Thats exactly what i tought, in particular the water at the start.
@@theq-1 In fact a water pipe is quite useful when explaning electrical circuits. Resistor is someone standing on a hose, current is quite obvious and voltage is the pressure as used here. With that in mind you can also explain ohms law and some other stuff and people understand the basic meaning.
Roichi R Imagine a water tank with pipes on opposite sides and a very tough elastic membrane dividing it into two chambers. Assuming the pipes and chambers are filled with water (a sealed circuit), if you pump water in one side, it seems to come out the other UNTIL the limit is reached, then it stops. But if you turn the pump off, the elastic force of the membrane pushes the water backward until the membrane is no longer stretched.
Further, if you connect this device in series with an alternating pump and a load, the “water flow” appears to go through the membrane if you make the pump reverse direction often enough.
Is there an analogy for a transistor in a water system?
@@frankgiancola7 Hydraulically operated valve?
The analogy with the water tank made this so much clearer than all the professors did in my 5 years of college. I knew a capacitor is just some kind of a fast charge/discharge "battery" and I knew the math behind it, but I didn't really understand what is actually achieved practically in a circuit using it and why it works. Thank you for providing this crucial info.
With one difference: You connect the water tank in series, but you have to connect capacitors in parallel, or it will cut your circuit instead of storing energy.
@@hamza-325 A better analogy would be a water tower since they are basically a T connection off the pipe at the bottom that allows pressure to force water up into the vertical pipe/tank. That is more analogous to the parallel connection and more analogous in the way they store the energy too. The water tower resists changes in pressure by converting it to potential energy in the gravitational field and visa versa. Thus they are good for smoothing out spikes in pressure much like a capacitor does for changes in voltage. Even better they also pass nothing in the steady state aka when the pressure within the pipe and tower are constant much like a capacitor doesn't when a DC circuit is in steady state.
It is a fairly small change in the analogy but makes it work even better for the task at hand.
great analogy
this man just explained in 10 minutes what my physics teacher cud not in an hour!!!!!!!!!! please never ever stop making these videos . you are a messiah to us future engineers😢
Teaching is not merit based -- public school teachers basically CANNOT be fired (unless they're convicted of murder, or something). There's a natural tendency to do the bare minimum.
On the other hand, on youtube... good educational videos get more views than half-ass videos... so there's an incentive to make the best videos you can. If you get 6 million views, you're going to make a lot more money.
See the difference?
After spending years and hundreds of hours trying to find out how electrical components actually work by reading through so-called "scientific" sources - who seem to intentionally just speak nonsense theoretical gibberish - your channel is like a breath of fresh air. You explain how these devices actually work in a clear, concise, logical form. Thank you so much for all that you do. Cheers mate.
you were reading above your grade level. These videos are great tool for introducing the subject to the masses but please don’t knock scientific and theoretical papers just because you don’t understand them.
the fact that you are watching this on CZcams is the very embodiment of scientific theory and theoretic “gibbberish”
@@smithjackson9210 "Above your grade level."
Nice appeal to authority and not-so-subtle ad hominem.
Oh and I fully "understand" "theoretical science".
I understand that it is a bunch of nonsense spewed by tenured cronies that can't hack it in the real world as actual engineers.
It is inherently based in fallacious reasoning - primarily appeal to authority.
Let me ask you this.
If the average person spouted what your average "theoretical physicist" says, would they be taken seriously, or rightfully called out as delusional?
"There are a bunch of 'quantum qbits' and 'black holes' and 'photons' that are simultaneously particles and waves and all this other stuff that you can't observe but trust me because I said so."
You would rightly wonder how they escaped from the looney bin.
But give them a PhD after their name and throw on a white coat, and suddenly they are the High Priests of Theoretical Science.
Another insane faith-based religion just like all of the rest.
Cheers.
@@justlolatthisworld7917 You claim everyone is using fallacies yet your whole argument is based on the logic that "I don't understand PhD level physics therefore no one does" which is just wrong. You aren't the smartest person on earth, whose knowledge of subjects is beyond everyone else, there are people much smarter than you or I who do understand PhD level physics and are making contributions to the world with it. Engineers and theoretical physicists are completely different people, studying completely different aspects of the same things, neither is a " cronie who can't hack it as the other". What composers are just cronies who couldn't hack it as singers and are now making up this music theory filled with gibberish.
Just so you know photons are easily observable, observing photons is how you vision works. Also black holes, while more astrophysics than normal physics, are also not that hard to detect by their massive influence on their surroundings, it is just impossible to directly see them as they don't reflect any light. And qbits are just units of info storage, not an actual thing. I have a high school level of understanding of physics and only cursory knowledge of quantum mechanics and even I understand that you know nothing of the subject and are in no position to argue about its contents.
I was ready to like you first comment, because a lot of scientific sources tend to love overcomplicated language and are made unnecessarily difficult to understand, it is the reason why these videos are so good but this science denial bullshit is just well bullshit
@@justlolatthisworld7917 Youre not very bright, and if you think this is all an electronics guy know about capacitors then you are very misled. Even in the first semester of basic electro the kids will learn how to calculate capacitor size for simple circuits and here you sit thinking that you know anything? Sorry to break it to you but this stuff is more advanced than you think but not too hard for the average kids in 1st year engineering. This video is BASIC UNDERSTANDING, its not skills any employer will pay you a dime for.
@@pflaffik LOL I've been making 6 figures doing back-end server work for a leading web hosting company for over a decade. I know more PRACTICAL electrical engineering information than you could ever dream. I've torn apart and built more computers than you could count.
I was freely admitting that the so-called "theoretical science" never made any sense to me.
I fail to see how that has any bearing on the real world. Cheers.
This is amazing. This is how this stuff needs to be taught in schools. You make it so simple and intuitive
Eh, if this was all you learned about capacitors then you would know almost nothing. If i give you some frequencies and a few specs for an audio filter, can you calculate the capacitors and resistors my circuit need? Because someone who learn this in school can. Be afraid of a little knowledge when it causes ppl to feel like they know everything, people with real knowledge are those who are aware of how little they know.
@@pflaffik you have a serious bug up your ass about this, huh? you should really lighten up! its not worth the 20 comments you've left on this video, because it just makes you look really lame
@@elliottwoods5636 Maybe? But he's not wrong.
What's taught in schools is crucial information, but at least in my engineering degree they didn't give these top-level summaries. Short explanations like these are so essential for contextualizing the equations and circuit diagrams
Science and technology should be taught by pasionate people
Very well done! Essential for those just starting out, as well as a refresher for those who have been at it a while, but might just need a little coaching on essentials of capacitance. Thank you!
I know mine is just one voice in a deafening crowd, but I just wanted to thank you for making a series of informative pieces that are comprehensive as well as comprehensible, and with such care to include references to other videos whose content may be useful in understanding this one. It's a very friendly format.
This is beautiful
Me as a child thinking capacitors as watertanks in those mini city pcb boards is right.
lol that is exactly how I named them
best comment, very innocent
I thought they were small explosives and batteries. I was right to some point. Aint i?
@@deadeye8 To some extent, sure!
Why overcomplicate things? This is so simple, a child can intuit them
This is by far the most best explanation about capacitors. Thank you.
Agreed
@@Mitch_C740 mostestest bestestest
From the depth of my heart, I just want to say thank you for this explanation.
I don't know why I understand scientific concepts more here on you tube than how how I did while in highschool 😂
A key concept that none of the other videos I've watched on electronics covered is that electrons travel back out of the capacitor's negative terminal.
I was under the impression that the electrons would jump across to the positive terminal once charged, and could then continue down the circuit.
Seems like an important detail to leave out!
Thanks for setting things straight!
You’re confusing conventional current with electron current
Or, that the elections require a circuit, and do not ‘jump across’ (regardless of methodology).
Possibly the best educational video to have been ever made about capacitors. Thanks for making this super clear and well explained video.
You're a genius! Summing up my 4 year degree in a few short minute videos.
lol
Is it really that bad?
@@mindhunter8772 I feel him, I also hold an electrical engineering degree, they teach you what stuff does, but not how they do it.
@@vintoncerf7562 This is why I'm more focused on Electronics Engineeing, at least, its more focused on Practical application of what you've learned
I have always found that when experts start using needlessly complicated explanations it's because they don't fully understand what they are talking about. This video is a breath of fresh air.SUBSCRIBED
HAAAHAAA you didn't get heart even though u tried to leech HAAAHAAA
How have you found that these experts don’t know what they are talking about?
@@Smiley957 bitter experience
I go great until the expert says, " this is theoretically how this works" because it can't be proven. Then I start on the alternative theories. Inside there are little men on bicycles making that motor turn, the electricity shocks them into action. Don't get me started on watts, steam and horse power. What kind of horse are we talking about. Appaloosa or Clydesdale.
Why in the world would someone thumbs down on this video?
As a beginer guide, you cannot get a better explanation. Yes he may have left out a few advance things such as capacitor reaction to AC voltage based on the frequency) etc.
Making this video is hard work. (All those cool graphics really drive the point home.)
Great video and illustration. First time watching. Thanks for sharing and keep up the good work.

Well some are fake, we will get thumbs down instantly, and seemingly automatically, when we post anything, before it could even have been watched. However, some are genuine dislikes but that's ok, it's inevitable that we can't please everyone and so we don't try to. Whatever we do someone will not be happy. The important thing is that the likes outweigh the dislikes substantially and so we'll continue to make free educational videos to help people out.
Wow I was so happy to finally find someone who really knows how to explain the subject he is talking about. I loved the video and learn allot. Plz keep teaching.
I just built my first circuit on a breadboard 2 days ago. Even for an absolute beginner, this was so easy to understand! I’ve watched other videos but this was by far the best! Keep up the great work!
I'm actually excited about learning about this stuff when I go for electrical engineering, I'm looking forward to learning a lot more in the upcoming years from you.
How sad is it that if I quit school and just watched videos like this for 6 hours a day I would be getting a superior education.
I was on a late learner and yes every think I know I've learnt from ABCTV learning programs for about 3040 years ago
Traditional education is gradually getting out of date and being replaced with online courses organized into learning paths as their quality improves.

This is the best video that explains what capacitors are, and what are the important things to know about them. Very concise and simple to understand.
This is the best explanation I have seen about capacitors, thanks a lot.
I think I agree with everyone else ,that the best explanation of capacitors I have seen. Watching that once think I understand what they do. 1st class mate.
I've watched over 10 videos on capacitors and honestly I wish I discovered this channel earlier thank you so much for the amazing explanation!
I failed electrical engineer a long time ago, and this video shown me why. a 8-9 mins video manage to make me understood something that took me 1-2 months to learn and still fail to understand 7:00, I know it turn AC to smooth DC, but not how it work (now I do). when we made our circuit, we got scold because we miss a lot of stuff was "implied" in the lecture (it nearly a decade and I'm still salty about it lol). Hard work pay off, but sometimes you just need a godamn good teacher to teach you the fundamental first. Thanks you TEM.
Amazing! I’m currently studying a physics course without a teacher and this is just so helpful! Thank you so much!
All the best!
Why do people think stuff like this has to be so difficult? I'm looking at you, the majority of youtube "explanations" and college professors. Thank you for providing to the point, understandable content!
My dad is an electrical engineer and I took an electronics course in high school, but neither my dad or my instructor could explain how capacitors work to me. I knew what they did, but I didn't understand how or why. It's all clear now! Thanks so much!
As a previous Electronics Technician, from the Vacuum-Tube era, I appreciate the way you explain with illustrations the concepts of components. Awesome Job! Thanks!
Thanks for explaining difficult things in a very simple way.
One of the best explanation I ever heard!
Looking forward to a more detailed look into the differences and application!!
Did this chapter a year ago in college but never understood what it actually does finally a year later an 8 min video explained it all. Brilliant
Outstanding! I learned more about capacitors in 8 minutes than in college. Thank you for taking the time to teach. You are very gifted.
I really love this channel. Explains everything so simple for non engineer person or should I say, for a normal persona
These 9 minutes are 1 week of my Electronics class
More like 4 years of college for me 😂
Been in the technical fields for 35 years and that's the best explanation I've ever heard. Great Job!!
Дадш
Can't express how helpful this is!
Absolutely cleared my doubts. Capacitor is no more strange for me.
Simple. Great explanation. Somehow, I always thought it was more complicated. Thank you!
I'm an electrical engineer and I could listen to you all day . Thanks bro
the AP classroom videos could NEVER explain things this well. thanks so much!
Oh my. If only we have youtube during my school time and well explanation from an expert. Can throw away all those thick textbook.
If anyone says "Here, catch" and there are two wires on the end, don't.
It's happened to me I was a young mechanic it was a large capacitor
Wow, for the first time in my life, I understood capacitor. Great job. You have earned a subscription.
Just discovered your channel today. I am a visual learner and I cannot praise you enough for how well you explained capacitors in this video.
Thumbs up and I will for sure be visiting your channel more frequently!
Welcome aboard!
Wow!!
I've understood more about capacitors from your video than I have understood from my lectures for the past 4 years.
this is one of the best explanations i've seen! thank you so much!
This kind of explanation couldn’t be more perfect to be honest. Great visuals that make everything clear. Go rly well done
Your explanations are the best i found on youtube. Thanks!
Could you elaborate on how the capacitor work in parallel with an inductor? Forming an oscillator?
I spent 15 years as an aircraft electrician in the Airforce. Your videos would have made the technical school much easier. And would have been a great learning aid for when we run into situations that me haven't seen in a long while.
Where were you during my school days?! 😜
The world missed another SN Bose. 😂
But still I’m happy that now it is part of my knowledge. 😃
Great Video, the ability to make complex issues simple is the mark of a good teacher, Thanks
This is probably the most pedagogical and well done video on the subject ever. BRAVO
I love this channel, I’ve always been curious to know how everything works and this channel answers many questions I’ve always wondered about but never looked into.
Ki
If we learn this concept in class full day we can't understand clearly but the small video understands clearly in less time. tq.
These animations are insane, I always hated electronics when I was at school in my Teens because I've never understood at all, I failed many classes.Then watching this video, I learned more than all those years, really incredible.
2 questions for you (or any other commenter who has knowledge or other videos to recommend:
1) what is capacitance? you covered the unit of measurement, but didn't talk about what it actually means.
2) how does a capacitor become overcharged? The analogy you used makes it easy to wrap my brain around the basics, but from your explanation it makes it seem like the capacitor will accept electrons until its fully charged, then by nature it won't accept any more electrons. If this is the case, how does one go about overloading it? If it's not the case, how it it usually prevented?
bonus question 3) does a capacitors rating need to match with some rating on the battery it's connected to?
I guess, Answer for question no:2 is Q=CV;beyond this charge, it may not be charged..
In the HVAC field, where I work, it is said that a capacitor allows for a time delay on electrical flow. We used to say "time delay on voltage", but that's not exactly right either. Either way, if I remember correctly, 1 farad = 1 second time delay when you have 1 volt flowing at 1 amp current. From there, you can do the math for any capacitor. Everyone likes to talk about how capacitors hold a charge, but they rarely talk about the length of time it takes for the energy to leave the other side of the capacitor, and that's what it's all about. It is just creating a time delay before the current is able to leave the other side of the capacitor.
I'm an formed Aviation Avionics Technitian. These videos are better than Most courses.
Me, a Brazilian guy, studying electronic/Eletric technical degree, finally could understand better how the capacitors actually works. My teachers are good ones, but each other has your own method to teach you. But damn bro, this video made everything clear
6:47 ElectroBOOM, GET OUT OF MY HEAD!
FOOL BRIDGE RECTIFIAH!
Exactly my thought lol
ah fuck good i thought i was the only one :O
I came looking for this comment
XD
Best explanation of capacitors I've ever seen , or heard of . The water tank illustration was so clear and easy to understand . thank you for the video
There are a lot of ridiculously poor explanations of capacitors on CZcams. This is by far the most practical and intuitive explanation I've seen. It would be nice to have a similar one that deals with the use of capacitors in an analog audio signal path.
CZcams videos could replace college classes. This is by far the best explanation of capacitors.
True
Great video! I worked at a company that made single use medical devices, mostly all sorts of IV bags. They used RF welders to make the bags by welding two layers of vinyl. I never really understood how these welders worked. There were a lot of capacitors used in the circuitry. When they didn’t work I would start checking capacitors which turned out to be the problem most of the time. From what I understand these welders work similar to radar or microwaves. Please consider doing a video about this technology.
Wish we had all these video animations when I was at school . All we had were books and blackboards and then had to learn stuff by rote without any intuitive understanding . This 8-9 minute video is just makes the concepts of capacitors and inductors (and its practical use) so much easier to grasp.
I've been studying the capacitors chp for a whole year but today actually found out what we really use it for.
Had solved more than 150 problems on capacitor without knowing what it actually is.😂
Thanks Engineering Mindset.
Problem solving skill is a good thing👍
That's serious thread to your future!!
The best 10 minutes of my day is spent with a cup of coffee at 6am watching one of these videos. Thank you!
Wow…how could you dislike this? Such a perfect vid explaining capacitors!!!!! Nice job bro!!!!!!
Good job man !
You’re doing a good work.
One time I accidentally touched a 230V capacitor ,
it just convulsed my arm but it
didn’t hurt .
Liviu Valache
cuz 230 volts with low amp cant burn but just make u feel it....if it has an amp ranging 2 and way above it might hurt a lot
@@endurofan9854 So you’re saying he has super powers?
Whoa.
Thank you for your video. I’m 17 years old and when i watching your video, i can understand clearly about capacitor an it makes me so excited.
You should try making your own salt-water capacitor! I made one when I was in your age, it was fun to play with.
I would charge it up using the static from the screen of my old CRT TV!
Way much better explained than any of our teachers at school
Thank you you made me love electronics
WOW !!! Im half way through second year and this video put so much together for me. great job guys !!!
μF is read mikro Farad and ''μ'' stands for the greek letter M on lower case. Just for the folks who are interested in the symbols. Thanks
Similarly, the 'Ω' symbol which is often used with resistors, stands for Ohm, but is actually the uppercase Omega, also from the greek alphabet.
Do you know why capacitors are rated in uF or pF and not in F

Neat and clear explanation 👏👏👏. thank you.
I been doing some electronics for years now and this video makes things so logical. The analogy with the water tank was like open the curtains... a very good way of explaining functions. There is no way of a possible missunderstanding thanks to your teaching skills. Keep it going!
Beautiful. Loving your videos and your pedagogical approach. You offer plenty of remediation which is great for an older student like me with ADHD. Much appreciated.
I feel like I should’ve known this along time ago. This is so simple. I’ve always wondered what a capacitors purpose was.
CJ
me too
🙄
Cause of the stupid curriculum
This is so detailed you even said the word 'Aluminium' the correct way
Absolutely love the analogies. Brilliant visualization.
This is how schools should teach.
Wel done. I've subbed.
I realized I want to spend the rest of my life building machines and robots. Your videos help me a lot in equipping my self with the foundations...so thank you. Hope I'll get there! 😁
I won't mention how many times I said "oh snap" while watching. These are things that I understand but the break down and the association with real life things is amazing. Thank you!!
Had to make a leyden jar for my physics project and this video really helped me to understand the concept of a capacitor.
Thanks!
In addition to polarised capacitors, there are also non-polarised capacitors.
Don't connect the minus side of a polarised capacitor to the plus of a load, or it'll blow up (like in the video).
Non-polarised caps don't care about polarisation and can be used in AC applications.
@John Smith Uhm yes, but if you want to be 100% sure you have to check the datasheet of the capacitor. There are several types of capacitors. The ones I encountered the most are these:
Electrolytic capacitors are always polarised, as far as I know these are always cilindrical.
Ceramic capacitors are non polarised, the "through hole" ones are mostly round and flat like a pancake, the smd ones (really tiny) are bars.
@John Smith Ah good luck ^^
My whole class struggled with this and this video was easier to understand than my 2 hr class
zombiegun71 it’s because teachers don’t all have equal talent, like any other profession. Your teacher was not very talented unfortunately.
this is amazing!
i learned all of this in college as an engineer and was clueless how we use it in real life, until now. wow
Credi di non avere mai sentito spiegare i componenti così bene. Sei bravissimo e molto chiaro! 👍👍👍
explain as crystal clear , thanks a lot
Thanks, James
@@EngineeringMindset Capastior shock is more dangerous for our body. Than normal electric shock 😲. So Discharge before to work with any capacitor.
