Question

v). Write any two difference between pnp and npn transistor.

Answer 1

1) In an NPN transistor, the current flows from the collector (C) to the Emitter (E), whereas in a PNP transistor, the current flows from the emitter to the collector.

2) PNP transistors are made up of two layers of P material with a sandwiched layer of N The NPN transistors are made up of two layers of N material and sandwiched with one layer of P material.

This is your answer . Hope this will help you .
