Question

When n – p – n transistor is used as an amplifier, then-

(a) electrons move from base to collector 

(b) holes move from emitter to base 

(c) electrons move from collector to base 

(d) holes move from base to emitter.

Answer 1

(a) electrons move from base to collector

When n – p – n transistor is in operation, the majority charge carriers, i.e., electrons move from emitter to base and then to collector.
