The Transistor is probably one of the greatest inventions in history. The things this tiny device enabled us to do are counless

[danielsau]

I love that you started explaining from the basics of the basics, that makes it easier to understand

[marclaurent]

I wanted to let you know that you do what a lot of my electrical engineering professors could not do for the life of them - and that is EXPLAIN WHY and WHAT is going on in a transistor circuit!!
THANK YOU FOR WHAT YOU DO! I’m subscribed and I keep up with all of your latest videos and watch ones you’ve already made. You’re the best in EE knowledge!!

Retired electrician/instrumentation fellow here. This is best analogy I have ever seen. Great animation! Great video!

THIS is the best 9:30 I have ever spent learning about electronics. It is so perfectly succinct and clear, with no redundant words - close to perfect instruction on the subject.

So why, over four decades, have I never heard of the conduction band? And I now also understand covalent bonding.

A beautifully curated iterative explanation of the subject from beginning to end. Thank you!!! So good.

I train new industrial mechanics in an OJT setting. I often refer my trainees to your videos because even if they don't have a clue on the topic we are dealing with, you explain it so that even an elementary student could understand it. I can get away with referring them to you even if they do have a clue while it might make them feel like I am being condescending toward them if I start so basic in person. Thanks for your work!

Absolutely fantastic! As oposed to many other similar tutorials, this one addresses the fact that the layers are doped with different amounts, which makes a huge difference in understanding. It also says what materials can be used to dope the silicon. This must have been created by someone who had missed the full explanation himself and then when he finally got it he wanted to share it with the others so that nothing is left unaddressed.

Could you make a video about star and delta in distribution system. When the exact connection is used and why.

[OslerS]

I was waiting for your exact video on this topic I think PCBs could come next, great as always!!

[LanceMcCarthy]

This is one of the best animatio s I've seen for depletion region a d forward bias.

[Android_Warrior]

This is the simpliest explanation of transistors I have ever seen, thank you.

[shinKOTSU]

This video came out just in time before my exam on motor controls. Was having a hard time understanding transistors.

[jamesallen]

Another perfect example of the need for science AND art. You use art (via video, graphics) to better teach a subject. Great video!

[yensteel]

God, you could nearly understand how logic gates could work already and wow, this is incredible engineering!

[mohammedsaifullah]

when i dont understand what my professors teaches... this is the best place to understand everything... thanks to you

[mahendraniwas]

Oh my god what a clear explanation bro...awsome work...thanks for taking initiative to make video

[okithdesilva]

Transistors are absolutely amazing! Without transistors the world would be a completely different place with no computers!

[onlythetruth]

Your Engineering Mindset, is SIMPLY the best.

Back in the days of using house antennas (90's), I once used some old telephone wire to bring it to my room. It was then that I learned the difference between just any type of wire and Coaxial cable. The old telephone wire was not capable of providing a strong enough reception, which I later replaced with coaxial which was infinitely better.
