Says transistors don't amplify signals, then describes exactly how transistors amplify signals. Brilliant mate, you done played yourself.

[@StormCentre88]

@Olav Viking @ Olav Viking. In some ways you are correct with your criticism, but I think you’re also a bit harsh on the narrator/video. Sure, you need a power supply and a base, collector, and emitter arrangement to amplify a signal presented to the BJ transistor’s base; agreed. However, the video depicts a (battery) power supply attached to the BJT. You're technically correct in that any “N” “P” “N” semiconductor (essentially 2 diodes connected together) transistor will not in itself form an amplifier. But the “N” “P” “N” semiconductor component is one of the most critical components (if not the most critical component) of an amplifier; and routinely technicians, engineers, and even discrete/other component catalogs refer to and/or list “N” “P” “N” semiconductors . . as “amplifiers”. The reason is; via varying the bias voltage presented to the base with an audio/other input signal they modulate the power supply rail voltage; and therefore provide an amplified version of the input signal to their emitter. Transistors are essentially active 3 terminal semiconductor devices act as either insulators or conductors depending on the aforementioned signal/bias voltage; and their ability to change between these 2 states means it has 2 basic functions; “amplification” (analogue electronics) and “switching” (digital electronics). I think the bigger concern with the video is the circuit arrangement towards the closing stages of the video; as the 2 stage transistor application has the emitter of the input/first stage connected directly to the base of the second stage transistor. In fact, the collector (not the emitter) of the input/first stage should be connected directly to the base of the second stage transistor. That said, I doubt too many people trying to learn how the transistor semiconductor works and relying upon these types of videos will understand analog/digital circuit design theory.

When discussing the transistor basics, it's crucial to understand that (a) the voltages of the 1st power and 2nd powers sources (PS) are not arbitrary, they are picked specifically from a very narrow interval of what a given transistor can handle. (b) 1st PS is picked such as that there is not enough push / pull from the applied voltage for electrons on the left N to overcome P and go to the right N, but just barely not enough. (c) 2nd PS adds just enough push to the left N and just enough pull to P to let the electrons flow over the junction barriers.

[@latzobear]

are you being sarcastice? please answer, I'm learning about this stuff.

[@Ezzell_]

no sarcasism. conventional flow is an old way(1880's) of labeling current flow when Benjamin Franklin assigned electrons flowing from positive to negitive...he just through lables on it....we found out later that that electrons move from a neg charged region to a possitive charged region. neg to pos. but before we knew this we labled our schematics with arrows in symbols thinking pos to neg. this was the conventional way of looking at it....and is now called conventional current flow....but the truth is that current is only the flow of electrons (sometimes in special setups electrons and ions can move to pos but this is rare) so we called it electron current flow. hope this helps

Consider a computer memory. The only terms which computer can understand is 1 & 0. ie; either on(1) or off(2). Now let's talk about transistor. If we feed a base voltage to a transisistor high enough the transistor starts conducting. We can call this ON state. if the base voltage we fed isn't high enough the transistor stops conducting which we can call the ' OFF' state. Computer interpret this ON state as 1 and.. OFF state as 0. That's how computer works, it stores info and stuffs like that.. Learning about Working of the transistor is pretty simple if we first knew why and where do we use it. Why the hell it has to act like a switch if we have a manual switch like the thing we use at our home?? Transistor is compact, doesn't have any moving parts and it is so so so so small hehe

Just incredible. I would put this video in a playlist with your other related videos so they all populate inside the video player and are easy to find. The algorithm on here sucks and none of your other videos are showing p for me in the related videos panel and all I want to see is more videos on the transistor as a switch that you mention, but now I have to go to your page and dig to find it. (which I will do!)

Philosophy student here and I suck at math or physics. Don`t understand almost any of it, but it is still an interesting video.

[@edgarcalochcampos1930]

Analog Human wtf

[@Maskddingo]

That sucks for you. Higher level philosophy is very logic centric, which in turn is directly related to algebra. You will need to eventually understand using laws to establish proofs, or you will reach a road-block in your understanding of your chosen line of study.

[@LockenJohny101]

That is because philosophy students are retards. Physics(I study that in 4th semeseter) is only my second greatest intrest after philosophy so I did 2 semesters in philosophy because we were offered to do so. Its a low effort useless degree, its an insult to philosophy that the word "philosophy" is used by you "people".

[@simeoncannalte3016]

Yo guys don’t hate on this guy holy shit. Not everyone has to study math and physics. I know hella lawyers who studied philosophy.

[@stephentoth6003]

LockenJohny101 Man i wonder if he learned in his Philosophy Classes, that appareantly all science majors philosophy on life is "be a condescending prick"

Perfect explanation.Thank you.🙏🙏🙏

"REQUEST": Make some videos about Thyristors

[@denv5221]

Thank you Sir, you are the only one who got the skill, the talent to make me understand with your diagram, what a transistor really is. I'm a beginner, and for three days I have been watch about a transistor on youtube and what I notice after was that their explainations doesn't even tickle my brain! Thank you very much again. Ty

"lets replace the slilicon with 4 handed smilies" lol but why?!😅

[@Gallzatron]

Seriously. It made it even harder to understand because I was trying to quell the potential nightmares I may have had upon seeing them

[@Cittamatra]

Because many people feel daunted when confronted with technical subjects, presented in a purely functional, dry manner. The introduction of a visual representation, which induces a sense of fun and light-heartedness within the mind, causes feelings of dauntedness and inability to diminish, therefore removing some of the obstruction to understanding.

[@darrenparis8314]

Well, I am certainly not forgetting it!

[@sicelogumede6295]

rich111 lol I was like what

[@neckslicer]

I think it was to try and make stuff a bit easier to digest into your brain. For me I will definitely not forget a 4 handed smiley anytime soon in my life!

[@chaseramos4865]

I can't focus because I'm laughing at the four handed smiley

"This is a clear case of current amplification!" Nothing is clear about this sir.

[@solapowsj25]

If you use a small power to open a tap, a large volume of water would drain out. Clear water example for gain OR amplification.

[@blusky3591]

the current is amplified because electrons are flowing from both the batteries and not just one battery

@@blusky3591 i didn't see any batteries, but 2 diodes

[@blusky3591]

@@endurofan9854 I must be referring to 2 duracell batteries you can see in 5:10 . I might be wrong so if you feel like correcting me, please do.

probably the best and clearest video I watched about transistors, thanks!!

Dude i still didnt undersand half the video

[@dulminperera3762]

2:39 The CC setting (subtitles) tell 'inside' instead of 'n-side'. I know it's a negligible issue, but just in case if any one (new to this topic) got confused.

[@badalkumar4775]

Wow ! Although, I knew about diodes and transistors but this animated video just enabled me to visualise the physics behind it. Great video 👍👍

[@SanskarTOP_G]

If you are a 12std student from India,this video is very good.It contains the entire chapter of semiconductor,in a simple and short form.

[@madagalaharivardhan9412]

One doubt pls: at 5:22 the animation shows electrons coming out from base,but the current direction indicator which is Arrow is quite opposite to flow of electrons explain why?

[@SanskarTOP_G]

@@madagalaharivardhan9412 Current always flows in the direction opposite to the flow of electrons.
