    The unit of specific conductivity is:

    A)  \[\Omega \,c{{m}^{-1}}\]                           

    B)  \[\Omega \,c{{m}^{-2}}\]           

    C)         \[{{\Omega }^{-1}}\,cm\]           

    D)         \[\Omega \,c{{m}^{-3}}\]

    E)  \[{{\Omega }^{-1}}\,c{{m}^{-1}}\]

    Correct Answer: E

    Solution :

    \[Specific\text{ }conductivity=\frac{1}{specific\text{ }resistance}\] \[=\frac{1}{\Omega -cm}={{(\Omega -cm)}^{-1}}\]
