    If \[L\] denotes the inductance of an inductor through which a current \[i\] is flowing, the dimensions of \[L{{i}^{2}}\] are                                          [CPMT 1982, 85, 87]

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

    B)             Not expressible in \[MLT\]

    C)             \[ML{{T}^{-2}}\]    

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

    Correct Answer: A

    Solution :

                    \[\frac{1}{2}L{{i}^{2}}\] = Stored energy in an inductor = \[[M{{L}^{2}}{{T}^{-2}}]\]
