- A brief Introduction to Capacitors, a few of their uses and simple Mathematics equations starting at 7:00 minutes
I have to buy most items myself to make these video's so any help would be greatly appreciated "become a Patreon" / markusfuller
men thanks to you ,I was graduated of electrician , and then in electronics ,but was too long and am trying to give back my knoledge to do some project I have in mind... I am absorbing all tutorials that I don't remember well...
Thank you Markus! Almost 30 years of playing guitar & ten of synth/electrical diy self learning and fun... I never realized the tone pot on a guitar was so simple! Doh! Thank you very much mate!!!
Brilliantly clear and helpful.
+Taren McCallan-Moore thank You Taren
I went to college for audio engineering, and this is a great refresher. It makes me want to find my notes on resistor color codes, as well.
Thank you Marcus
Very valuable insight of Capacitor working n changing its values etc.
As an HVAC Apprentice this is very helpful! Thanks a bunch!
mate, you make learning fun! This was simple (for my simple brain) and easy to digest. you put a lot of work into the illustrations and I applaud you for being detailed with that. years ago in one of my cars I had a huge subwoofer and I had a 1farad cap on it. it really made a difference in the bass notes and saved the dimming headlight syndrome when heavy bass notes hit.
Clear, concise, comprehensive, and great examples! Thanks for a great video!
you are fuckin amazing man..I tell you.. you are one of the top best teachers on youtube
Cheers for another informative & understandable video Markus.
Thanks again for taking the time to share & educate.
Incredible videos! Going to be working my way through over the next week or two
Dear Markus, thank you very much for your clear, detailed yet easy to understand videos. Much to learn from you! You should write a hands on book for understanding synthesizers, etc...
+Ivor Kadragic Hello Ivor. ThankYou, I wish I had the time to write a book. I do not know everything but Im always learning new things myself. Best wishes from Markus.
Subscribed. Very informative videos, thanks for taking the time to make them
I enjoy your tear-downs and instruction as you have done here. About polarization indications or markings, I found that negative/positive marking are often misleading. We must validate using a meter to obtain and to validate true polarity. Thumbs up on this one.
Bobcatt22 Thank you Bobcatt22 . I do still have a mishap of figuring out the correct way to install a new cap now and then.
Here is a video on the polarization markings of caps: czcams.com/video/BnR_DLd1PDI/video.html
Great teaching I did understand quite easily
0:52 Unless it's a tantalum capacitor - they are marked on their (+) lead, just to make things confusing.
Excelente tutorial for beginers!
Your vids are great. Always informative and engaging. :)
Thankyou very much Paul. theres more on the way :-)
I really love your channel, I've seen many videos because I love synthesizers and some day I hope to build my own. Watching this video has taught me so much and I'm constantly getting new ideas. Thanks Markus!
+Alexander Downes Thankyou Alexander I hope you manage to make a Synthesizer, if you look around the internet there are many useful pages with details on certain parts of synthesizers and their circuit diagrams for VFO LFO etc. I keep thinking one day to make one myself. I made one many years ago but it was not really very good but I should try again sometime. Best wishes and do let me know how you get along.
Keep watching these vids and thinking the same thing, want to build my own synth thou not sure how much all the basic coponents would cost. Been scanning through the maplins book and say hmmmm for far too long lol.
there is a book called Make: analog synthesizers the isbn number is 978-1-449-34522-8 I believe it should be available on amazon and shows several circuits on how to make your own synth plus you can buy a ready made circuit board to make the synth on the front cover.
+markusfuller .Oh wow really thanks ill check it out even i dnt ending building something lol. Im sure it will be a veeeery intresting read thanks again.
Wow! Refreshing my memory on what I've learned in school 'bout this in only 14 minutes. Thank you. :-)
Great teaching. Thanks alot!
Hi Markus,
Thanks a lot for this really interesting video. It's really great to learn both: English and Electronics. Even I'm totally beginner in electronic, I' ve really enjoyed your teaching. Best regards from France.
TheGilounet Thankyou very much. It is never too late to learn anything. I am still learning new things every day and i am almost 50 years old :-). Best wishes from Markus
markusfuller Hi Markus. You're right! Thanks for all this kind words :)
Thanks Markus, great video! It took me back to my days in Electronics 1 in college. I'd love to see more videos about electronics principles. Maybe inductance would be a great next step if you wanted to make another video like this. Thanks again.
Hi Matt. Yes Inductors is the next step though I'm just trying to get some spare time so i can get started. Best wishes from Markus
What an amazing video. Well done. I learned a lot, thank you!
excellent work.
thank you for your clear and practical explanations ! : )
thank you very much for this brilliant explanation
Hi Markus, have you ever considered doing some videos on how to hook up these discrete components to make, say, a simple oscillator or a filter? You explain things well & I think that a lot of us subscribers would be interested in how an analog synth is implemented.
+Jandro Kirkish Hello Jandro, I have thought about it but its just getting the time to experiment and make the video's thats the problem. I still have some of my own old circuit diagrams from years ago that could be used for the basis of synthesis. I will certainly think about it. Many thanks from Markus
Great tutorial.
Thanks Markus for a brief but clear explanation/introduction to capacitors. I have a question: sometimes on printed circuit boards, we'll see some copper traces that look like the diagram you showed of a variable capacitor. Especially in circuits with high frequencies in them. Is that some sort of capacitor made with the proximity of those intertwining traces to maybe filter out some harmonics between traces or am I completely off base with my theory ? Thanks in advance for any reply.
Hello Alain. You are correct Capacitors can be designed directly onto PCBs, also Sometimes those traces are there just to make the track longer and give a slight delay for the signal so if some components are closer than others but the the signals need to reach the destination at different times. and if you have them in strange shapes they are to filter certain frequencies, a lot of black magic goes into designing them and I wish I knew more about them. Dave Jones of the CZcams EEVblog shows a teardown of A spectrum analyser and explains those strange etched patterns on the circuit boards. I hope that helps a little. Best wishes Markus.
Awesome video as usual, I was hoping the next one after resistors would be capacitors too :)
But Markus, do you think you could make a video that talks about the interaction of AC frequencies and capacitors like for a guitars tone control?
Do a similar video, but this time testing different capacitors and how they affect or degrade sound in electric circuits such as preamps or synths. That would be interesting. For example does switching form 1uF tantalum to 1uF electrolytic affects the sound. I am very skeptical toward it, but it would be cool to test it (as long as they have exact same value). I've heard some people swear by the "sound" of WIMA film capacitors, whatever they mean by that.
Id really like to know the same thing. Which would help me understand why some synths sound far larger than other.

Thank you! I forgot most of this stuff from my schooling. Don't use it, you loose it!
Perhaps one day you can explain how super capacitors working with lithium batteries - having a very small footprint, can actually jump a 12v car battery. Secondly, the overall impact on technology utilizing super caps.
Perfect speed and complexity
Maybe cautioning people not to put there fingers on the really big caps would had been a good idea, those things can zap your heart off.
anyway
Really informative , it answered somme question that I had a while ago…
what about maximum voltage rating ?
Love it, Better than my physics teacher. though he was one of the best.
I have a question not sure if you can answer. On a AC capacitor you have alternating current and other youtube videos say that the the positive charge alternates from one side of the capacitor to the other giving the illusion its passing current. If this is true then why when the positive charge alternates to the other side is it not discharged into the common/ground? No one has been able to answer that question
cosmocasper Hmm not quite sure I can truly answer that question. if you have a positive and negative charge which is alternating then I'm guessing neither one is the actual ground in a permanent way else yes you would be right to say that the positive would go to ground during that half cycle period of the alternating current. Yikes that is a good question I have never really thought about it as I normally use polarised caps in the synth projects that I do. I will go and look into it myself as you have me curious now.
How can electrolytic capacitors which are prohibited from being reverse-biased be used as coupling capacitors?
"ooops" :)
when you attached the LED to the capacitor it lit up and slowly dimmed, But how do they make camera flashes where its a sudden quick discharge?
+Four Side Gaming. hello The LED had a resistor attached so it slowly discharged the Capacitor. without the resistor it would discharged so quickly that the LED would have been damaged.
Thank you
How do you find the F of an unknown capacitor. Someone sanded it and painted removing info. Closest i can guess from size is about 1F to 2F.
Hello if the value is not on the Capacitor then the way I would try and find out is using a capacitance meter and measuring it. you cannot really tell the value by size or shape. and sadly if the capacitor is dead you will get no value and will have to try and find schematic diagrams of the circuit which can sometimes be many hours on the internet (sometimes they are not even available). I had one blown off the board and destroyed once but luckily that section of the circuit was cloned several times on the circuit board so I guessed by looking at the cap used there to replace the cap that was missing. but generally there is no easy answer.
It's a bass amp cap.
thanklyou, i was just askng ymself this question of "what does a capacitor do?"
very informative altho i got lost after some of the math....
Dude, which university do you teach? I would like to enroll.
nice viedeo
mr thanks..please you can help me, I need check a capacitor to 68000 mf 40 vdc + - 20 %...who test this capacitor, don't have a osciloscopio...say hello to ecuador
Hi Ivan, you do not need an oscilloscope to test capacitors. you can use a multimeter that has capacitance check on it or better an actual LCR or ESR meter. some modern multimeters have a reasonably good Capacitance measurement range on them. other than buying something like that I do not think there is another way to get any accurate measurement, If you are not sure about buying a device to measure the Capacitor then the cheaper option would be to just buy a replacement Capacitor and change them over. that would be the cheaper option. sorry I have no other way to help. Best Wishes from Markus.
Lol "oops"
Good placement
I love you
+John Tenezaca Thank You very much :-)
Love your work Markus... Lots of clever visuals.
I just had a thought while watching your whiteboard illustrations... If this product does what it says on the packet, you could draw the some of the circuits, which would provide some pretty impressive visual feedback! www.amazon.com/CircuitWriter-Precision-Pen-silver-based-grams/dp/B00B88B9KI
I've never used this myself though, so I can't say how well it works, but still it might be worth looking in to?
Hi fkthewhat. I just looked at that pen, looks interesting, I could make up an actual working circuit with that. but i could not wipe it off afterwards and reuse the board. but you still have a good idea there . Thank you
Ouch, my head hurts...
De-mystify capacitors. Thanks!
