Bipolar Transistors

Bipolar Transistors are a solid state, three-pin devices made from three layers of silicon. A bipolar transistor is designed to amplify current, bipolar transistors can also function as a switch. There are two main types of transistor, PNP (positive negative positive) or NPN (negative positive-negative).
