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.
My guess is that he doesn't do the maths. He tells you what's going on with words and drawings. Bookwriters and lecturers have a tendency to - as they already understand the workings of things and you're supposed to be able to calculate stuff regarding the subjects - rely on maths to explain physics, and this is a very shite thing to do as it misses out on some very graphical things. Sure, if you look into it, the equations imply that a depletion zone exists and that a diode carries current better in one direction than the other, but the mathematical description for the motion of electrons isn't an efficient way of allowing you to understand the concept.
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!
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.
If you have any issues understanding some words, just turn on "CC" closed caption and select your native language from the settings menu (gear) for a better understanding. :)
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 :)
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.
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.
Very well explained. I was having trouble teasing this out of a textbook and you made it clear in 10 minutes. Thank you for the time and effort to make this video.
Ben, one of the best demo's on transistors i have seen, and I have seen a lot of them. Great job! I'm subscribing to you and look forward to seeing your past and future videos. Thumbing-up
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.
This is the only satisfactory explanation of the workings of the transistor I have seen -- and I have seen many, either on video or in text form on the internet. Thanks Ben!
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.
Thanks! Ive watched many other videos on this BJT and I didnt quite understand, your video was so clear and helpful, I finally understand how it works :)
Good qualitative description of what's going on. Liked it! One description that I always found useful to understand transistor "action" is that once electrons from the emitter enter into the base, they are now "minority" carriers in the p - type base region, and will as such be swept across the reverse biased base - collector junction and into the n -type collector region.
Great explanation I must have read more than 20+(LONG) articles on Transistors, but the subject was always fuzzy. This video clears thing up greatly , thanks.
This was so clear. Omg your voice your explanations are sooo good. I don't know anything about computers and have set myself to learn as much as I can and I've watched so many videos but they all lacked something. This one didn't, it went in depth and you didn't skip and steps to explain anything.
Well done Ben, I was able to follow the whole video start to finish and I don't have a single question left :D (I'm usually someone who has a lot of questions left after an explanation :P)
Learning how a transistor works from someone who uses the conventional flow while he explains it with elektronflow is very very hard! You did it right! Thx!
OMG. dude, that was absolutely worth an applause. i wish you were teaching my ELT classes (years ago of course). it takes time to find a gem of a teacher. okay- here he is.
@bigote in simple terms the emitter side is negatively charged while the collector is positive and the base is neutral. Current only flows through the transistor if you apply current through the base and emitter. This is because the emitter gets filled up with more electrons (from the base to emmiter circuit) to the point it can jump (difuse) into the base because it has no where else to go. After that the base becomes negatively charged. Then the collector which is positively charged attracts the negative electrons from the base and completes the curcuit
I think you've just clarified a fundamental point in electronics that has always confused me when thinking about these things, and even more when listening to explanations of it, and it's so clear now that I feel stupid for never considering the difference. You clarified it by making such a big deal about the distinction between conventional electrical flow and the real flow of electrons. The distinction between these two perspectives carries such a massive weight that almost nothing considered in one perspective translates directly to the other, even if they are descriptions of the exact same mechanism. Thank you for unveiling maybe 1% of the mysteries of electricity for my crippled brain.
Pretty clear explanation, it's been a long time since I studied and tried to figure this out for the first time. It's kinda electrons were fooled to get into the base and then abducted and kicked out to the collector XD Congratulations!
I knew early on that my career (now behind me) would be in the liberal arts. But my father raised me to be a lifelong student and that meant curiosity...even about things I have no real grasp of. So that hasn't stopped me trying to learn at least something about the hardware that I've been using professionally and personally...and your videos are revelations for me!
Thank you! That's the clearest explanation of the workings of an NPN transistor using electron flow that I've discovered yet. It would be terrific if you would do a follow-on video on how a PNP transistor works using electron flow, which makes much better sense to me than conventional current flow, a fiction that defies science. Thanks again Ben!!
