When n-p-n transistor is used as an amplifie

Options

A. Electrons move from base to collector
B. Holes move from emitter to base
C. Holes move from collector to base
D. Holes move from base to emitter

Answer

A

Explanation

For an amplifier to behave as n-p-n transistor, the collector is maintained at positive level. Thas the electrons move from base to collector.
