    The dielectric constant of a perfect conductor is

    A)  \[+1\]                     

    B)  \[0\]

    C)  Infinite                

    D)  \[-1\]

    Correct Answer: C

    Solution :

    Dielectric, constant of a perfect conductor is infinite\[(\infty )\]. Therefore, electric field inside a conductor is always zero. We cannot have electric field lines inside a conductor.
