This is How Diodes Work

In this video, we're going to learn how diodes work. We're going to start by reviewing the basic properties of diodes, and then we'll move on to discuss how diodes are used in circuits. By the end of the video, you'll have a basic understanding of how diodes work and what they are used for!

Best explanation of the chemical/atomic level action of conductors, insulators and doping of silicon.

Wow! I've always known that diodes keep electrons flowing in one direction but never knew how it actually worked. Thanks for the video!

This is similar to the explanation my College profs gave in the Electronics Technician program I graduated from in 1979. For some reason this explanation makes a ton more sense than it did back in 'college. Obviously this explanation is enhanced by using the animation and thus easy to understand. After 43 years I am finally able to claim I UNDERSTAND how diodes work rather than just forward biased the switch is on and in reverse biased the switch is off. It is true, a picture is worth a thousand words, and an animation is the pathway to understanding. Great job. Three thumbs up. First time I have ever given more than two thumbs for anything.

Nicely done. I have a PhD in EE and couldn't have done it better myself. Cheers!

[revolutionaryprepper]

This is exactly how a diode works. Ty for this explanation!

[kenlogsdon]

It is also interesting to note that in the reverse bias mode, the size of the depletion region can be changed by varying the applied voltage. This results in what is known as a "varactor" or "varicap" which is basically a voltage controlled capacitor, useful in RF tuning and other applications.

Thank You, your explanations and diagrams are clear and easy to follow, I always look forward to watching more of your videos.

That was an awesome video, really gave an excellent explanation on how diodes function. I always knew they were very simple devices, but I didn't realize that it was literally just a piece of p-silicon attached to a piece of n-silicon. That's crazy!

[rustys]

Amazing, thank you. Very nicely done. I knew what diodes did (roughly) but after that it was all new. Every day's a school day as they say.

[nicevideomancanada]

Nice explanation, I understood all the way through.

[princequestly]

What a fantastic explanation. You definitely earned my sub. Good stuff.

[donerickson]

This is great. Maybe I missed something but it said the energy has to be more than 0.7v and the battery shown is 0.5v

[charlespierce]

Very well most of the time. Just don't let the smoke out.

[LAYATORS]

4:44 how does the diode itself act as insulator in that specific moment?

[ggesdsdsdsd]

This is also pretty much how a LED works also! Nice video

[primus]

Put enough voltage it will allow current

[SAJAN_ECE]

When Electrons migrate from N side to P region and Holes migrate from P side to N region, they recombine and Ions with Positive Charge and Negative charge will be present in the Depletion Region. The Electric field is caused by the Immobile Positive and Negative Ions. Needed some clarity in that portion.

[estebanruiz]

This is an awesome explanation! I will have to watch it a few times to fully understand the concept, but thanks for making this as easy as it could be to understand. I am looking forward to showing these engineering videos to my now infant son in the future, to help explain how the these things work

This was my actual question to my high school electronics teacher. He tried to explain it, but this explanation with graphics is top-notch. My teacher even gave us the exam with my question being the last with a 10-point bonus if answered correctly. I only got 3 points for my understanding.😁
