    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.
