Question
When npn transistor is used as amplifier
Options
A.electrons move from base to collector
B.When npn transistor is used as amplifier
C.electrons move from collector to base
D.holes move from base to emitter.
Solution
When npn transistor is used, majority charge carrier electrons of n type emitter move from emitter to base and then base to collector.
