    Metals have

    A)  zero resistivity  

    B)  high resistivity

    C)  low resistivity   

    D)  infinite resistivity

    Correct Answer: C

    Solution :

    Resistivity   \[\rho =\frac{R\,\,A}{l}\] \[\Rightarrow \] \[\rho \propto R\] \[\because \]  Metals have low resistance, therefore they have low resistivity.
