What is the purpose of the following semiconductor crystals in a transistor: emitter, base, and collector?

What will be an ideal response?


The base is always in between the emitter and the collector. The transistors used in automobiles are called bipolar transistors. They have two polarities, electrons and holes. A transistor is either an N-P-N or a P-N-P type. Each layer of the transistor has a connection for an electrical lead. The emitter is the input lead; the output lead is the collector. The base layer, in the center, controls the switching function of the transistor.
