    What is the resistivity of a pure semiconductor at absolute zero?

    A)  Zero                

    B)         Infinity

    C)  Same as that of conductors at room temperature

    D)  Same as that of insulators at room temperature

    Correct Answer: B

    Solution :

    [b] The electrical conductivity of a semiconductor at 0 K is zero. Hence resistivity (= 1/electrical conductivity) is infinity.
