Transistor Theory
Bipolar junction transistors (BJTs) and field-effect transistors (FETs) work basically the same way. The voltage you apply to the input (base, for a BJT, or gate, for a FET) determines whether or not current flows through the transistor (from collector to emitter for a BJT, and from source to drain for a FET).
Jul 14, 2016 This video demonstrates working of a Bipolar Junction Transistor (BJT) with it's practical applications such as transistor as an amplifier and as a switch with help of animation. INTRODUCTION - A transistor is a small electronic device that can cause changes in a large electrical output signal by small changes in a small input signal.That is, a weak input signal can be amplified (made stronger) by a transistor. For example, very weak radio signals in the air can be picked up by a wire antenna and processed by transistor amplifiers until they are strong enough to be.
To get an idea of how a transistor works (specifically, a FET), think of a pipe connecting a source of water to a drain with a controllable valve across a section of the pipe, as shown here. By controlling whether the valve is fully closed, fully open, or partially open, you control the flow of water from the source to the drain.
You can set up the control mechanism for your valve in two ways. The control mechanism can
Act like an on/off switch, either fully opening or fully closing with nothing in between.
Open partially, depending on how much force you exert on it. When it’s partially open, you can adjust the valve a little to allow more or less water to flow from source to drain; small changes in the force you exert on the valve create similar, yet larger, changes in the flow of water. That’s how a transistor acts as an amplifier.
Kardashian baby. Thank you Lord for every moment. I’ll be happy, of course, I simply can’t understand where the time goes. “I’m sad time is flying as fast as it is. “Is it weird that I think I’m having anxiety thinking True will be one on Friday?!?!” she tweeted in April 2019.

Bipolar transistors work in a similar way: The base acts like the controllable valve shown, controlling the flow of electrons from the emitter to the collector (or, in circuit-speak, the flow of conventional current from the collector to the emitter). By controlling the base, you can turn the transistor fully on or fully off, or you can allow small changes at the base to control large changes in current from collector to emitter.
