An NPN transistor is a three-terminal semiconductor that amplifies weak signals to strong ones. In this transistor, the majority of charge carriers are electrons that move from the emitter region to the collector and it results in the formation of current. So this NPN transistor is sandwiched between two N-type material layers. Based on the construction, these are separated into two categories PNP and NPN. Transistors are made with silicon (or) germanium based on the application it is selected. … [Read more...]
