    In a transistor, forward bias is always smaller than the reverse bias. This is done to

    A)  maintain constant current supply

    B)  get good output

    C)  avoid excessive heating of transistor

    D)  maintain flow of majority charge carriers

    Correct Answer: C

    Solution :

    In forward biasing, the majority charge carriers would move from emitter to collector through the base with high velocity. This gives rise to excessive heat causing damage to transistor.
