    Serious draw back of the semiconductor device is:

    A)  they cannot be used with high voltage

    B)  they pollute the environment

    C)  they are costly

    D)  they do not last for long time

    Correct Answer: A

    Solution :

    The semiconductor devices does not work at high voltage. The conductivity of semiconductor is affected in the varying voltage of semiconductor device (it means the resistivity of semiconductor device decreases with increase in temperature). Hence, this type of drawback is a serious drawback of semiconductor.
