When npn transistor is used as an amplifier
Options
(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
Correct Answer:
electrons move from base to collector
Explanation:
When npn transistor is used as amplifier, majority charge carriers/electrons of n-type emitter travel from emitter to base and then from base to collector.
