  • question_answer
    The unit of specific conductivity is:

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

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

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

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

    Correct Answer: D

    Solution :

    (d) \[{{\Omega }^{-1}}c{{m}^{-1}}\] \[\text{Conductivity=}\frac{\text{1}}{\text{Resistivity}}\] Its unit = mho/cm or \[{{\Omega }^{-1}}c{{m}^{-1}}\]
