Brief Introduction Transistor is a semiconductor device having three layers, three terminals and two junctions. Since we have only two types of semiconductors i.e. the p-type and n-type, there are two types of transistors: they are NPN transistor and PNP transistor. It is named as transistor which is an acronym of two terms: “transfer-of-resistor.” It Read More
