Transistor

Transistor : A Transistor is a device that regulates current or voltage flow and acts as a switch or Gate for electronic Signals. Transistor consist of three layers of a semiconductor material each capable of currying a current.

Types of Transistor: Transistor are basically Classified into two types they are Bipolar Junction Transistors (BJT) and Field effect Transistors (FET). the BLTs are again Classified into NPN and PNP Transistors.
