Definition of Transistors
A transistor is a semiconductor device that performs the function of signal modification or switching. It consists of three layers of semiconductor material with a different position of answer forming an emitter, a base, and a collector. The operation of the transistor depends on controlling the inflow of current between the collector and the emitter through the base.
