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

    A)  transistor

    B)         p-type semiconductor

    C)         amplifier

    D)         n-type semiconductor

    Correct Answer: D

    Solution :

    Phosphorus and arsenic belong to \[V\] group i.e., they are pentavalent and give electrons for conduction in semiconductor. So, they form \[n-\]type semiconductor on being added to a semiconductor.
