pwm amplifier

Transistor and how to use it in the circuit

A transistor is a three-pin electronic component which its main function is to pass the current from two pins according to the other pin (along with current amplification). Transistors have different types, but we are going to examine the bipolar type here. The two pins which the current passes are called the emitter (E) and…
