Can gears rotate them selves, can gears rotate for long without using any electric power or human power
Please do a video on solar panels 🙏... your videos are perfect 😇

Only 99 remain
Seen our new video on HOW SOLAR PANELS WORK in detail czcams.com/video/Yxt72aDjFgY/video.html
That was, by far, the best explanation of how LEDs work I have ever seen.
Super in depth, while not talking over our heads.
It was too redundant -- it felt like 4 or 5 shorts edited together. How many times do we have to be told about the flat side of a diode?
@@christosvoskresye As many you need to learn
I got here referenced from Derek's ( Veritassium ) video "Why It Was Almost Impossible to Make the Blue LED". So cool.
Well done. This explained Diodes in minutes what took days for my professor in college to do back in the ‘80s.
CZcams doesn't exist in 80s
@@animetalksinhindi660 he wasn’t implying that
didn't
because Cathode Ray Tubes were all the rage back then
@@animetalksinhindi660 obviously sherlock
Another LED type that I learned about a few weeks ago is called an addressable LED. It’s a bit beyond this video, but worth noting for the advanced users as it allows multiple LEDs to be controlled at different colors each using only one signal pin on a microcontroller.
It is a LED with an internal microcontroller that can be gotten as either RGB or RGBW and is controlled by a high low signal. The LEDs are chained in sequential order by their signal pins. To control them, a signal is sent containing the information for all the LEDs in the chain. The first LED removes its instructions and then sends the remaining signal to the next LED. These LEDs can be bought individually or in LED strips.
You are wonderful, man. Explaining such a wide spectrum of electronics, in such brief lucidly.
Thank you, glad you like them. Lot of hard work goes into them
@@EngineeringMindset God bless you, team.
LED's are basically amazing stuff. When I was little I only saw LED in red or green, and they were very dim, only useful for indicator lights on various machines.
Then someone invented blue LED and now LED has basically replaced light bulbs.
Best video i have seen so far informing us about LEDs. Thanks very much for high quality content and the effort put into it. I really appreciate you supported your theoretical background together with circuit diagraghms and also making it on breadboards just to let us see how it looks. It definitely would tale a lot of effort and time. That is very much appreciated.
Thank you, very glad you enjoyed
@@EngineeringMindset hey bro can u start a series on hydraulics if u have the info please
@@khaoticman3055I second that!
@@nicksanchez3020 facts
I love how, when adjusting the ratios of GaAs and GaP (GaAsP), you had the audience GASP every time the light came on.
Subtle, yet beautiful.
This is one of the best videos I've ever seen. Easy to digest for any level of familiarity of sciences, with amazing infographics. Keep up the great work.
I absolutely love the pace and information density in your videos!
Seriously? The pacing is almost rabid and the content should be able to do the work without the needless whoosh-zippy distracting stuff. Definitely made for the ADHDTV generation.
For a long time, LEDs could only be produced in the colors infrared, red, orange, yellow and green.
It was not until 1990 that blue LEDs and thus also white LEDs could be developed.
I know that back then cars used blue bulbs instead of LEDs for high beam indicators.
Credits to Japan
It was so hard, in fact, that the three Japanese men that discovered how to make one, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, won a Nobel Prize in physics!
hands down the best explanation of LEDs from start to finish. this needs to go on the reference shelf. thank you sir.
This was extremely fun and engaging, thank you so much for the high quality content mate
You should do a video on "Toasters explained - How toasters work...and why you shouldn't put silverware into the slots" from an electrical engineering perspective. The electrical engineering behind the average toaster is both fascinating and horrifying. The toaster is probably the single most dangerous standalone appliance in the average home. While microwave transformers are far more dangerous/lethal and the large capacitors found in A/C units can also deliver a lethal charge, you have to disassemble those appliances to enter danger territory. The toaster, on the other hand, can deliver a lethal charge without any disassembly and can also short itself out and even cause electrical fires. The toaster also has plenty to cover on the electrical engineering front despite just being a bunch of metal and wires.
An incredibly well detailed video& very well put together. Cheers. 👍
The explication of the n and p type materials was so clear. I don’t think I’ve ever seen it done that well. Bravo!
Excellent video. Being an old TV, RADIO. Repairman in the 70’s I have a steep learning curve ahead of me. MOSFET was the cutting edge of the cutting edge when I started Medical School. Now at age 70, I am still seeing patients but am getting back into electronics. In my life as a physician, I met many veterans from WW2 and into the early 1950’s. Learned a lot once their NDA’s expired. Amazing what they were able to do with vacuum tubes! Now, something I would appreciate your expert opinion.
I learned physics in undergrad, Kozarev’s theories, which he proved to a certain pin extent, were fully validated in the Mid to late 80’s and 90’s. The physics of his Spiral mirror are amazing but well beyond my math level. I found out last year of a recent experiment in the last 10 years, they were able to SEE the Pleiades where they currently are both with light telescope and radio-telescope when using the Kosarev spiral mirror in conjunction. The Pleiades are 1200 light years away. This would indicate that Kozarev’s mirror is able to receive tachyons or other similar particles. There is a documentary on CZcams about the experiments that were tried in an area of low magnetic field near the North pole. Please let me know what your thoughts are on this scientifically proven but quire mysterious device. My name is Sergio AKA Dr. T🖖🏼
See my new MOSFET explained video here➡️: czcams.com/video/AwRJsze_9m4/video.html
Brilliant video, Paul, full of explanation and detail. Just the thing to get young brains excited. Thanks for sharing.
this is much better than textbook definitions, he explains everything perfectly
Amazing super condensed info about LEDs. Best video on this topic I've ever seen.
My teacher used your video in class.
a whole semester of my College (30 years ago) condensed in 20 minutes 😄
awesome explanation😉
Truly thank you for this ..I have wounded my hole life the science behind the led but every time I researched I got the basics of power gose hear and light ...not a single person on this planet in 30 years bothered to actually go deeper... So truly thank you 💖
Nice video, very well put together!
I have learned that before. But the way you explained, makes the learning more enjoyable/fun making electronics more interesting for newbies. Very well explained and great video.
This is the best video I ever saw that explains so much info about LEDs! Well done 👏
awesome video man, seriously this was a good one also thanks for that heads on it, i appreciate that :)
Is it just me or is the theatrics of these vids getting better and better?! Great edit and info I learn so much from you!
I was pleased that your animation showed the correct electron flow direction from negative to positive. In electronics college our instructor demonstrated this with a piece of graphite and a piece of paper. With high DC voltage and the negative connected to the graphite the arc produced carried graphite particles to the paper as the arc continued through the paper to the positive electrode on the other side.
You are correct in that the electrons originate from the negative terminal and go towards the positive terminal
But the electric field originates at the positive terminal and ends at the negative terminal. The direction of the electric field is opposite to the direction of the electron flow.
I like that too, practically it doesn't matter when thinking about circuits, but I would have loved if that was what I learned in school to begin with.
In those days that was referred to as
Conventional Current!
Confusing Indeed!! 😮❤
Very informative video. Especially the infographics and animations help a lot to understand in a better manner
Look who's back.😊
This is such a simple, highly informative video. Very easy to understand. Great video.
Such clean videos, amazing content !!
I learned more in this video than I have learned in years of being taught electronics elsewhere. Well done!!!
Very informative. In fact, brilliant! I'm astonished that scientists think of this stuff and make it work!
Very good explanation with amazing animation easily understood by anyone.
Amazing video and easy to follow. Thank you!
Amazingly explained, thank you Mr
the ONLY video that I could find that actually answered my questions! Thanks
If someone plonks a mug of coffee with "Watts up?" written on the side, onto your working tray, the tray will always tip to one side. but the led won't roll off - that's what the flat bit is for.
Really great insight, to those who want to learn about semiconductor basics
appreciate these cool, in depth videos
I appreciate the content of these episodes so much, I actually watch the ads.
I have absolutely no reason whatsoever to learn about how LEDs work but your video was so good and so entertaining that I did it anyway and I don't regret it.
The ftat section is for determinig correct polarity of the led.
Lovely video mate.👌🏾
Thanks for this lesson❤️
Most computer monitors are still LCDs which do not use per pixel LEDs.
This is such a detailed, amazing video.
Great video please continue with common electronic components
That is realy nice and clear elaboration.
Hats off to u man ... Love the explanation of how really an semiconductor works..
I love it. This one saved to my play list too. 😊✔
9:12 the smell of a burning resistor is something you never want to smell
Very nicely explained!👍👍👍
Thumbs up for the, "Awww" @ 16:41 🥰
This is one of the best videos on LEDs explained. Dayum!!!
How interesting it is that this video came out right before I completed a class on this topic.
Very well done Sir!
your work is fantastic. thank you a lot !
Thank you for this amazing video!
this is the best explanation, thanks
Wow! Very informative video. I didn't realize LEDs are that interesting!
Wow. Everything I wanted to know about LEDs! Thanks.
The best explanation ever, you make it so easy to understand
Keep going bro
I know its lots of work to do and even more to edit the videos, and that sayed Resistor, multimeter and this vid. i like most. Most informative in my mind. Thank You.
Thanks, I've been trying hard to improve the content recently. Glad you enjoy them
I have been struggling understanding this since my untermediate school from now on i can explain to my brother. Thanks for your excellent expalantion. i was amazed.
Great explanation with excellent illustrations. Even a person who is not having much knowledge can understand .
Very nicely done. Cheers! 😉
Very interesting! A lot of information!
Holy cow. I've neve seen so much relevant information packed into a video without feeling overwhelmed. How long did it take you to put this togehter?
Great description! 👍🙏
Could you make a video about oscillators? I'm curious to learn more about them.
Also, what is a photon? I can see the light from my remote control with my naked eye, does that mean I can see infrared light?
Humans can see infrared light under certain conditions.
Infrared light has longer wavelengths and lower energy than visible light.
The human eye is made of water, which absorbs infrared light at wavelengths just slightly longer than the deepest red color that humans can perceive. However, if infrared light is bright enough, and of short enough wavelength, then humans can perceive it as red.
edit: that was bard, I am no that smart
FANTASTIC video! thank you!
Super informative and very high quality video!
Beautiful video! ❤
Another brilliant explanation video.
By far the best explanation of LED I've heard
Nice...its too much usefull💕
Thank you very informative and easy to understand.
This was amazing. So cool to know more about guitar pedals clipping works lml
Best ever tutorial on LED working principle. Thanks a lot sir.
Glad you think so
Excellent explanation, thank you.
That was a great video!
Correction on your part LCD screens are made of the same semiconductor that cameras use to take photos/videos however if you open the screen of a broken phone, tablet, LCD monitor you'll see a row of smd leds on a flexible strip at the bottom of the screen.
The fact you gave about the remote is actually how I check the batteries in my remotes by aiming them at my camera and pressing a button
thanks for referring me to this, I still wonder how much you'd need to break an LED if you wire it up the wrong direction
but it has answered so many other questions
Excellent, well explained ,very knowledgeable session, all the best and keep it up..
Great video...!
Best explain
Keep up
Wow great video✨💕
awesome video! 👍
Very informative, that’s why I’m a subscriber! 🤓🙃
The best explanations I have found ❤❤
coming from the Veritasium video i was hoping the Blue LED construction would get more love but it was hardly mentioned
Very nice! I'm sharing this. 👍🏻👏🏻🙋🏼♂️
Fascinating 👍
That last section about coloring is hilarious XD
Thanks for letting me know about this video. It's really great, pack full of informations.
Nice vid! Thank you.
8:36 those are not tiny LEDs inside the computer monitor, those are LCD pixels that are backlit with a few white LEDs. If you went to a large sports stadium and zoomed into their large screen, yes then you would see lots of LEDs that make up the picture, but thats not the case with an LCD computer monitor
