When npn transistor is used as an amplifler

A

Electrons move from base to emitter

B

Holes move from emitter to base

C

Electrons move from collector to base

D

Holes moves form base to emitter

Text Solution

Verified by Experts

The correct Answer is:
A
When `NPN` transistor is used as an amplifier, majority charge carriers electrons of `N`-type emitter move from emitter to base and than base to collector.
