    Dimensions of self-inductance are

    A)  \[[ML{{T}^{-2}}{{A}^{-3}}]\]  

    B) \[[M{{L}^{-2}}{{T}^{-1}}{{A}^{-2}}]\]

    C)  \[[M{{L}^{2}}{{T}^{-2}}{{A}^{-2}}]\]   

    D)  \[[M{{L}^{2}}{{A}^{-1}}]\]

    Correct Answer: C

    Solution :

     SI unit of self-inductance is \[\frac{N-m}{{{A}^{2}}}\] and its dimensions are\[[M{{L}^{2}}{{T}^{-2}}{{A}^{-2}}]\]. But its practical unit is henry (H).
