This is one of the BEST tutorials I ever seen. You make other people life easier, as you have a talent to translate science to be understandable. KUDOS TO YOU !!

You are one of the very few people, who actually knows how to explain something complex and difficult, clinging to the bare bone basics for it to still make sense while not overwhelming with new information. I believe your concept of explaining - first let's talk about what it does and how you can use it, then we can dig deeper into the theory and advanced use cases - is how teaching should be done in general. Like foreign languages - the classical method is trying to force vocabulary and grammar into the students, lesson after lesson, leaving little room for conversation and text comprehension - ignoring the fact that this gets you nowhere near to what usually is the goal of learning languages - to be actually able to communicate with foreigners, to be able to get around by yourself while abroad etc... It's mind boggling, yet very few schools and teachers make any effort to change the dysfunctional way of teaching. Ok, rant over - I just wanted to thank you and compliment you on your superb teaching skill :)

Duuuuude. This is, without doubt, the best explanation I've seen. I "sort of" knew how they worked, but all the pennies dropped while watching this. I totally get it now. Thank you 🖤 (bookmarked to revisit when I inevitably forget!)

WHY DO YOU ONLY HAVE 893 VIEWS.... I WAS SUPPOSED TO LEARN ALL OF THIS THEORY IN COLLEGE BUT YOU'RE EXPLANING EVERYTHING WAY BETTER THAN ANY OF MY GRADUATE LEVEL PROF'S TAUGHT ME.

That’s by far the best explanation of a transistor that I have ever heard. I have an EE degree and wish that my professors would have broken it down so simply.

"Anything I can say is just gonna make it worse" This is true wisdom

I'm really glad youtube algorithm has put this video high in the search ranking even though it's not one of the most viewed on the subject. Absolutely fantastic explanation! You're supremely skilled at understanding the shenanigans people go through while learning this stuff and have a simple way of navigating around them. It truly is simply put, I applaud you and thank you kind sir!

FINALLY, someone explains this in a way I can understand. Thanks! You explained it super-fast, but I was able to keep up. 🙂

I really like the explanation! One of the best ways I have ever had. The video editing cuts distracts me a little bit. But I think I can live with that.

This is absolutely amazing. Thank you so much!

Its always these rare less than 5k views videos that really make you understand the subject

I am glad you didn’t mess up your markers: it’s so irritating when that happens

Superb explanation... everything is there

Thank you for simplifying the topic. Hope you channel grow . you deserve millions of subscribers.

You my friend are a life saver, I don't know how you explain it so easily but I dig it!! Thank you I am definitely subscribing so I can refer to all of your videos

Wow again, second video and it's just what I need. I don't need all the theory at first, I want an "operational" understanding so as to build circuits and have fun. That's the path you chose to take and take us through and it's ruthlessly logical to do so, rather than waiting for an hypothetic aha moment after suffering with theory. All schools should teach this way!!

Really loving your videos - I’m an older guy doing an electrical engineering degree (later in life than most!) and your explanations just WORK for my brain to absorb. Thank you man.

finally I found this video after 1 year of torture with confusion, thanks sir u really help me :")

Me: I got an exam next week, could you teach me an entire semester of electronics by then? Simply Put: Hold my beer. I Love this guy :D

So incredibly good explanation. Your videos are Simply Awesome :) Don't know how many transistor videos I have watched and maybe I am just dense but finally I get it 😁 Loads of thanks 👍

Great, indeed.

I don"t know if you would even respond to questions....especially from a video 4yrs ago, but, there's one thing I am having trouble with in your explanation. How can I forward bias, JUST the base to emitter? Without forward biasing the collector as well. I get that, they are two separate JUNCTIONS (not Diodes), but if I am applying V/I to the base, am I not biasing both collector and emitter? And then is the answer to provide enough voltage to either open the emitter only, or open both the emitter and collector? Is that what you were saying? And to add...thank you for your in depth analysis and creative tutorial analogies. I enjoy watching and have learned a lot...perhaps not enough :)

Great explanation. Thank you! I really wish you would put more "natural" pauses or spacing in between your sentences instead of cutting the videos "tightly" because it sort of makes it harder to follow. I had to keep backing up, listening to what you said, stopping the video to let it sink in, and then continuing... not being critical at all... just letting you know that "I" personally feel it would be better with a few more breaks between sentences/thoughts.

Tell me about it. I had a problem with opamps, but I finally got it. Transistors is just chaos to me.

Sorry, but new to electronics. With an NPN transistor ; am I correct in assuming that if I use 12v and the correct resistor through the base to achieve the 0.7v it will open the gate for the 12v to flow from base to emitter. Is this to save energy ?

Perfect

The idea of vacancies in the Valence band as positive charge carriers *can* be pretty problematic. Even the simple theatre-aisle-shuffle is not quite right, as electrons in the Valence band "move" in the same "direction" as the vacancies, in that sense they are more aptly compared to a bubble floating along on a stream. ("move" and "direction" in quotes because the very idea of electrons and atoms as billiard balls starts to break down here... the fact of the matter is that they are all occupying crystal momentum states with the same sign)

What are Common base amplifiers used for mostly? Common base amplifiers input is the collector and the base is the output which only amplifies the current 1:1 ratio? The difference between a PNP compared to an NPN is that the PNP has less output and lower electrons compared to an NPN. The PNP transistors have issues with thermal runaway compared to NPN?

Would you have any interest in doing a video on vacuum tubes and their historical relation to transistors? Your explanations are great, and I would even be willing to send you some vintage tubes free just to see your explanation.

nice videos! thanks for share

Thanks. Finding your videos very helpful. Do you have an index of videos? Looking for an overview on buffers. You mentioned them in a video on amplifiers to protect circuits.

I never understood the concept of INVERSION, THE PHYSICS of what is really going on, 'INPUT SIGNAL INVERTED 180 OUT OF PHASE' IN A 'COMMON EMITTER BJT AMPLIFIER'.

Never stop man please lol

think junctions not diodes think junctions not diodes think junctions not diodes think junctions not diodes think junctions not diodes think junctions not diodes think junctions not diodes think junctions not diodes....

In my opinion, there is absolutely no way to clearly explain a transistor unless you know how each is made, and I do not mean you have to name the stuff ( the so called impurities, you know like no longer pure, no longer virgin), but most importantly the role they play, and therefore the characteristics that it gives to the transistor. Once that is crystal clear in the mind, then the mind can put together the rest. Otherwise it is nothing but memorizing, period. The reason memorizing happens is because one does not understand. There is no way around it. From that, then it becomes obvious what the P and N actually do, and those arrows of diode as to which way they, inward, outward are for kids. They are a mess of confusion and meaningless nonsense. And to make the whole thing more cluster f***k, there is the whole confusion as to which way current flow ( that is another gueralla in the room, oh my), knowing the make up, it will once and for all also clarify so call BJT from so called Mosfet. What on earth current and voltage in regard to this impurity associated with the base or whatever, collector, emitter, source, drain, gate,...... oh jee wiz mean. And if explained correctly, it will alsoclarify this other crap mean, it is always there in 99.90% of circuits, ground up or ground down... or whatever show off bulleying lingo goes with that. Up resistor, down resistor.. shh***t I don't even know what the heck it is called. [ Oh my pull-up and pull down resistor, just barely came to me as my mind was racing to find the hollywoodish terms) For instance are the collecor and the emitter made of the same stuff. In other words if you removed the base, would the transistor behave as a simple conductor, or short circuit or whatever. Of course not. If it was so, they wouldn't be having different names. The two N,s and the two P's are not the same, nor does the base or gate mean as is represented by P or N to mean that.

Dude, you confused the hell out of it in your quest for simplification.

Talk too fast ! Hard to understand. See the Organic Chemist for a good example.
