Question

Brief explanation about PNP & NPN semiconductors

Answer 1

Answer:

In an NPN transistor, the flow current runs from the collector terminal to the Emitter terminal, whereas in a PNP, the flow of current runs from the emitter terminal to the collector terminal. PNP transistor is made up of two P-type material layers with a layer of sandwiched of N-type.
