Answers

Answered by varunkotian23

Actually Transistor acts as only a variable resistor. The value of resistor between Collector and Emitter is changed by the base current. The Transistor acts as a Regulator (Variable Resistor) or a switch(ON/OFF). When a Transistor acts as a Regulator, it is called an Amplifier.
