    If phosphorus and arsenic impurities are added to  a semiconductor, then it will be:

    A)  transistor        

    B)  p-type semiconductor

    C)  amplifier      

    D)  n-type semiconductor

    Correct Answer: D

    Solution :

    Phosphorous and arsenic belong to V group. Hence, they are called pentavalent and give electron for conduction in semiconductor. Therefore, they form n-type semiconductor on being added to a semiconductor.
