Question

what are pnp and npn transistors

Answer 1

NPN and PNP transistors are bipolar junction transistors, and it is a basic electrical and electronic component which is used to build many electrical and electronic projects. ... The main difference between the NPN and PNP transistor is, an NPN transistor turns on when the current flows through the base of the transistor.

Answer 2

$\huge\boxed{\texttt{\fcolorbox{red}{aqua}{Hey Mate}}}$

In PNP transistors, majority charge carriers are holes, whereas in NPN transistors, electrons are the majority charge carriers. ... The main difference between the NPN and PNP transistoris, an NPN transistor turns on when the current flows through the base of the transistor.
