Bipolar Junction Transistor ( BJT )

Bipolar transistors are semiconductor devices consist of three electrodes; the emitter, base and collector. Like diodes, bipolar transistors can be constructed of silicon or germanium but silicon is the most popular. Bipolar transistors are commonly used as amplifier and electronic switch. There are two types of bipolar transistor, NPN and PNP.
