    When n-p-n transistor is used as an amplifier:

    A)  Electrons move from base to collector

    B)  Holes move from collector to base

    C)  Electrons move from collector to base

    D)  Holes move from base to emitter

    Correct Answer: D

    Solution :

    When forward bias is applied on n-p-n  transistor, then it works as an amplifier. In forward biased n-p-n transistor, electrons move from emitter to base and holes move from base to emitter. Hence, the correction option is [d].
