Transistor Working Basic

Transistor is 3 Terminal electronic semiconductor component/device. It has three terminals named as BASE, Emitter And Collector. Transistor name meaning lies in its own working. Trans + istor = Transistor The prefix trans tells about signal transfer from low resistance to high resistance part and istor means solid physical structure having property of resistance. A transistor has a 3 sandwich […]
