Not sure if it was mentioned, that PNP transistors are commonly used in audio power amplifiers as a complementary pair on the output end, working in a push/pull configuration of the signal.

One of the best, simplest, and most straight-to-the-point demonstrations I've seen. Obviously excluding the backwards battery

I actually disagree.. since power seems to actually work from neg to positive. And not from pos to neg. I think it is more accurate this way.

he has the Positive terminal of the battery connected to the ground symbol, and has labelled it negative, while the negative terminal of the battery is labelled positive.

As an Electronics technician for the last 25 years, my job primarily has been to troubleshoot why something isn’t working, having a basic understanding of electronics principles and experience with tons of failure scenarios has served me well. Scrolling through the videos on here today I found yours to be the only one that brilliantly and simply explained transistors, I loved the imaginary jumper explanation of how the transistor works as a switch. When troubleshooting any electronic device the first rule is simplicity! Example - if your receivers FM band isn’t working doubtful you’ll find the problem in the amp section. Well done sir!

Five vids in and you are the one that nailed it. One guy even showed how to wire an NPN when he was in fact using a PNP......confusing as hell. I was following along on my breadboard. Nice video, clear explanation. Keep it up.

Not sure that you realize - by this time (May 2019) your video is the best on KZread explaining how a PNP transistor works. You don't explain how the electrons flow inside the PNP transistor but providing that one knows how the electrons flow inside a NPN transistor (plenty of videos about that on KZread) and from all the other details that you clarify it becomes obvious how the flow of electricity from Emitter to Base allows the PNP transistor depletion zones to open up for higher current flow. Thank you very much!

@GreatWhiteNiko. You know about this stuff. Does the base need current or just voltage? I am trying to make my first pulse motor which is like the HOLY GRALE for me.. The base gets its jolt from spinnin the rotor (with magnets attached) near a coil. The NPN opens and lets trough a big puls of current to magnitise the coil. This pulse of magnetism pushes the rotor along. I think I got the theory down but in practice.....

@@captainprototype187 Oh no, don't get me wrong. I am just starting to learn electronics. So far I'm at the level of "how it works" but literally nothing practical. You need to ask someone else. Your question makes me wonder too - does the base need amps and voltage or just some so-so voltage?

@captainprototype187

5 жыл бұрын

@GreatWhitwNiko. Lol, you sure sounded like an expert! I think I got the answer now. The npn has 2 circuits built in. The first, trigger, circuit activates the bigger circuit. So you put the positive lead on the base and the negative goes to ground. That makes the first circuit. And every circuit draws a current. Furthermore, every vid calls the transistor a current drawing device. I found this vid that helped me a lot. kzread.info/dash/bejne/nYKKw6uqna67n6w.html

@@captainprototype187 Well, today I asked a friend of mine that is an electronics guru about the very basics of transistor use. What he told me was unexpected for me. See if you learn something practical too: 1. Bipolar (PNP and NPN) are used to REGULATE current. Used to control motor speed for example. 2. FETs (MOSFET) are used as switches - just turn on/off the current. Not sure in what applications they are used most. I see them in TV circuit boards all the time. If they are used as switches it'd make sense to assume that FETs are used in computer chips but I apparently speculate here. Also: 1. Bipolar - the gate uses CURRENT - From 0 up to 0.7A. You vary the current (Amps) of the gate and the big current from Emmiter (Source) to Collector (Drain) varies with it. 2. FETs (MOSFETs) the gate use VOLTAGE. Because what you want is to "pressure" up the area that creates the magnetic field which "opens" the flow of current from Emitter to Collector. And FETs basically work like that - you supply voltage and they do nothing. You increase the voltage and they still do nothing. Then at some point they let all the current flow. So that's a "digital" type of operation - 0 or 1 - closed or open. That's why they are used as switches. My friend also said that all the details about electrons/holes, and depletion zones are not needed at all when you actually work with electronics. The movement of electrons etc are good to know and cool to know but once you start practically using the components that goes way way in the background. But to me it is about feeling confident about my knowledge so I like to learn stuff like that. Good luck.
