    When NPN transistor is used as an amplifier [AIEEE 2004]

    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: A

    Solution :

                 When NPN transistor is used as an amplifier, majority charge carrier electrons of N-type emitter move from emitter to base and then base to collector.
