How does a Light Emitting Diode or LED work?
A SIMPLE explanation of Light Emitting Diodes (LEDs). Learn how an LED works, its working principle, and the difference between it and pn diodes. If you want to learn more about Light Emitting Diodes (LEDs), check out our in-depth post at: www.electrical4u.com/working-principle-of-light-emitting-diode/
Light Emitting Diode which we also call L.E.D is nothing but like p n junction diode. Nowadays L.E.D’s are most widely used in semiconductor diodes. This diode emits light when it forward biased. Normally this diode is formed by a p n junction. This is the semiconductor p n junction. This diode has two terminals anode and cathode.
This is anode or positive terminal. This is cathode or negati...

Faraday's Laws of Electromagnetic Induction
Просмотров 125 тыс.6 лет назад
We have discussed here Faraday's Laws of Electromagnetic Induction. This law says when a changing magnetic field links with a conductor, an emf is induced across the conductor. If the conductor is the part of a closed circuit, a current flows through the circuit due to the induced emf. The induced emf is directly proportional to the rate of change of flux linkage with respect to time with the c...

What is Self Inductance? A Simple Explanation
Просмотров 37 тыс.6 лет назад
A SIMPLE explanation of self inductance. We discuss what self-inductance is, the equations that govern it, and go over an example. When we apply alternating current to a coil alternatingly changing flux gets produced surround it.This changing flux also links with the coil itself from where it has been generated. The changing flux linkage with electrical conductors of the coil causes emf to be i...

Wow ❤ video is really helpful but why this channel don't post Video???
I’m watching in June 2024
Such a simple short and amazing explanation thank you
the background music is very disturbing.it makes the tutorial very tiresome to follow.
Just a doubt how and from where did the first power transferred equation came wich you just differentiated and equated to zero for max power transfer ?
tq so much it's very helpful, animation of working helps us to actually visualise and understand it's hard to visualise and understand just by reading
Thank you it helped I am officially out of the deep dark black and back In my usual black
Hello vktc
Thank you sir
Complicated 😢😢
Sir, My childrens were searching the answer for last 1 year....At last you explained it very well....Thanks a lot sir...
سادس 2025
Very good sharing 👍🏻
Please upload videos about dc mechine
You explained very well
I can understant your english i saw lots of animation electrical video but i understant a littlebit but understand your words easily
Thank you sir 💖💖💖💖🙏🏻🙏🏻🙏🏻
greate , thank you for sharing
Hi there😮😮😮😮😅😅😮
Hjfjtnbiirnfjir
10 year in video now in 2024
Conventional flow sucks, why has humanity not yet dumped this arbitrary concept?
Super Video, l Had Understood In Clear Way 😊😊
Clear and lucid style explanation , now I know the working principle of a MOSFET. Thank you very much.
Striking graphics
Flow of electron arrow is wrong.
Thank you so much❤
Bruh tooooo slow animations but not bad
very nice video on xmer magnetic circuit. really very hard labor to elaborate the phenomenon.
Who is watch video in 2024😂
Who is from 2024
It's understanding is vary easy😊😊
Sir you explain the right thing I also considered with it but I think if you tell the matter about Lenz s law why the rotor always try to catch the rotating magnetic field
Very clearly explained.
Great explanation.
I learn something new every day.thank you for keeping this simplified .
Here anode should be of pb not of PbO2
2024😂❤🎉
Allah razo olsun ya hiçbir yerde yok aw şu deney .hintliler yetişti yine yardıma
So basically in zener diode at breakdown voltage covalent bonds are broken and hence no. Of charge carriers increase leading to increase in current??
Nice 👌
Thank you so much sir you explained the whole in just 2 minutes 🙏🏻
Why not just correct it instead of making something incorrect the "convention"?
Great video
Straightforward interpretation！Thanku😻
Thank you for the video
Great video, but, frankly, you could choose a better voice over. This one sounds like it is from the 80s, when they just started developing this feature....
Just wow explanation 👏 ❤
