How Transistors Work - The Learning Circuit

one of the best explained ....thank you so much...

In just 7 min you cleared every thing. Teaching is an art and that's true.

It's like a tap water valve. There are 3 elements in the valve: inlet, outlet and valve control. If you want water flows from inlet (emitter) to outlet (collector), you open the valve control (base).

Nice vidos

Thanks very good briefing

Information in video is far too fast and then free ebook is basically behind a personal information gathering exercise and requirement to create an account.

Why vcb - vce > 0,7 , conduce the region be, in PNP ??

But nowadays ic makes learning difficult.f u would thought about IC

Thanks

wow that was so fast & so confusing we never got to see a transistor what going on the Question was What dos a transistor do & how dose it work Pars a look at one wuld be advantages, keep the dilogy simpal & bring in semantics once we know what we are looking at.

You have the knowledge but you are a bad teacher toooo fast

Well done

pnp ????????????? omg this is a crucial quick lesson....thanks.........

love your videos---I know its an old video, but I recently built a 3.5v regulator using a BJT with a 4.2v zener diode on gate to control gate voltage...input is 9v. The problem I'm having is that my math and the results don't seem to correlate. Using a 4.2v zener, (500ma ) and 1k resistor...I am getting output of 4v. I think I should be getting 3.5 or so...(ie--.7 volt gate drop)---but--I end up getting 4v! It's driving me crazy!. I work with MOSFET's all the time and find them very easy to bias and use. HELP...I am obviously wrong in my calculations

How do I test a selector valve handle on an aircraft cargo door that has a transistor symbol in it's drawing? It has three positions, 1) Open 2) Off 3) close. It does two functions, it mechanically ports hydraulic fluid to either the open or close plumbing.......and in either open or close it turns on the hydraulic pump to provide pressure. It doesn't directly turn on the hydraulic pump.....for safety it goes through the LGCIU computer so the hydraulic circuit will not work when the aircraft is in the air. So it is the LGCIU that controls a relay to actually turn on the hydraulic pump. The selector handle sends the signal to the LGCIU which turns on the hydraulic pump as long as the aircraft is safely on the ground.
The electrical connector has three pins which are shown in the drawing like a transistor. In the drawing one of the legs of the transistor doesn't seem to connect to anything. I think one of the connector pins (C) is unused. But that can't be right for a transistor....can it? I want to be able to test the selector handle to see if it is functioning electrically. How do I test that transistor in this selector handle?
When I have an assistant hold the selector in either the open or close position, I get nothing on my meter in the diode setting. But I know the transistor works once other wiring problems were repaired. But just to eliminate the selector handle early on in troubleshooting.....how do I test it electrically? Thank you for any help you can provide. Oh yeah, on the drawing I can see the side where 28 volts should come in and that voltage is in fact present on the Aircraft side of the connector. But activating the handle results in no continuity when the meter is connected across any two pins in the selector receptacle. (which is the way the LGCIU computer looks at it.)
Shouldn't the selector handle simply provide continuity in the open or closed positions? Why is it so confusing to test?

what happens if you apply 20 volts on to base of the transistor?

As the collector base junction is reversed bias Even current flows through the collector from emitter , base and to the collector then how we can say that in collector no current flows because this is and reversed bias

i always mix symbols and electric direction in my mind.. it takes time to understand

Very nice way to lecture. Understand easy

great

the best transistor tutorial.

Awesome...

NPN means...The Arrow is Not Pointing In...PNP means...The Arrow Points In Perfectly!

terima kasih puan. Moga Allah sentiasa merahmati puan

Why Vbe is 8.3V??, there is no voltage drop in the LED or in the resistor??

เยี่ยมครับ

Wow, this is amazing you deliver it in a unique and short way. Thank you, god bless you.

I invented the Darlington transistor 😄🙃

Hi Loves, could yall please make a video about creating a PCIe card? In the video id like to see accessing the PC's PCIe memory addresses via C code. Turbo C++ or DJGPP/Watcom would be perfect. Im looking to create a double SPI port card for VR. thanks!

Are you alien from a super galaxy for beyond our planet earth nature has gifted you a vast 0101010101010101 memory chip I say for you a long live.

Please explain VCC and VBB

She is talking very fast. Cant understand her

You have the most perfect explanation about transistor using precise circuits

I'm still in shadow analyzing what really took place after + voltage was applied to base of an npn transistor..there must be a reason why current flows from imitter to collector when base was supplied + voltage.a concrete explanation.there must be an effect of positive charge applied to the base to the negative charge of the emmitter that cause the flow of electron emitter to base and emitter to collector.unlike poles attract each other.

Is it possible to connect more than two transistors form a Darlington pair using npn transistors

Can I use two separate batteries or power sources. Onefor base signal and separate battery for collector emitters?

You 'v got me on the right way, of the transistor. Thank you very much Karin..aptly great channel.

Darlington pair is now called transgender 🤣🤣

If you have a circuit with a transistor that is rated for 500mW but you want to raise it to a full watt, what are your options?

How to use
B E C of transistor

Thanks for tutorial

Forest Mims would be proud!!!!! That is Forest M. Mims not the "Massacre Forest Mims"

Great refresher. I used to dabble with semi conductors as a kid, but didn't really understand how they worked. This video brought it all back for me...thanks!

Very nice 👍 Gide
