What is a transistor???
PLz help!!!

Answer:
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
Electronics Tutorial about the Bipolar Transistor also called the Bipolar Junction Transistor or BJT including the Transistor Types and Construction.
A transistor is a miniature electronic component that can do two different jobs. It can work either as an amplifier or a switch: When it works as an amplifier, it takes in a tiny electric current at one end (an input current) and produces a much bigger electric current (an output current) at the other.

Transistors are also used to switch electronic signals. ... Most types of transistors are packaged individually but can also be included in an integrated circuit.
