How a transistor works

A detailed look at how an NPN bipolar junction transistor works and what it does.

I don't know what it is, but you consistently have the clearest explanations I've ever heard. I took an entire class on Analog Devices at my college last semester and walked away with a very poor understanding of transistors. But these two videos you have on semiconductors and transistors have clarified things so much.

This is the single best explanation of transistors I've ever seen. You are not afraid to go into depth, which makes it all so much easier to understand! Instead of using a bunch of useless analogies, you just tell me exactly what's going on, I appreciate it!

Im not an english speaker but i could understand perfectly about bjt for the first time! Such a nice explanation. Thank you

Damn. I have this phenomenon with your videos. You explain something I haven't heard, yet which I grasp the first time. Then you extend that knowledge and while you're explaining it my brain immediately thinks a step ahead and therefore I learn it myself and get immediate feedback whether that made sense. I love that. That is a teaching experience I'll never forget.

No one ever explained this concept in such an awesome way . came here randomly, but surprisingly learned a new way to see the transistor.
thank you very much :)

I have watched like.... 20 videos about how NPN transistors work and this is the only one that has made sense. Thank you.

I didn't intend to know how amplification works but the way you explained helped me figure that out as well!

[devikabsree]

This is the best explanation on how BJT works that I have ever heard or read from any book. Thank you.

[andrii]

The clearest explanation I've heard on diodes and transistors, answered all my questions, thank you so much!

[josefinej]

Thank you so much for making these videos. I'm writing a paper about the transistor and this really helped me a lot. You explain things without leaving questions like many others do, and I really appreciate that.

[toheedh]

one of the top and best explaination of transistor. loved how you walked step by step with each concept

[markproulx]

This is the clearest explanation of transistor operation I have ever seen. Thank you.

[lawrencetrincia]

Incredible explanation! You have a talent for making a complex subject very simple.

[Okie-Tom]

It is always better to visually see what's going on for learning. Thanks for the work in making this.

[michaelwilkes]

well thats possibly the best transistor explanation i have ever seen. simple and short and yet somehow still covered everything, including the doping difference between collector and emitter, which is kind of crucial to understand why the transistor doesnt work right if you flip it around.

[TangodownNZ]

You are the only person on you tube who explains this so people can understand it. Thank you

Currently sitting in my circuit analysis class bored out of my mind while the teacher is talking about calculating current in parallel circuits, decided to actually learn something. This is the best explanation of transistors I've found yet.

[heshanperera]

Thank you SO MUCH for making this video. I was taught about transistors from two separate teachers with multiple textbooks and I never got it. This 11 minute video was so articulate and clear where now I understand why npn transistors function the way that they function.

[xMonts]

For sure, the clearest and most complete explanation of a BJT on YT. Well done!

Thank you for making these videos. People like you are a treasure to this crappy world.
