    Inductance \[L\] can be dimensionally represented as               [CBSE PMT 1989, 92; IIT 1983; CPMT 1992; DPMT 1999; KCET 2004; J&K CET 2005]

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

    B)             \[M{{L}^{2}}{{T}^{-4}}{{A}^{-3}}\]

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

    D)             \[M{{L}^{2}}{{T}^{4}}{{A}^{3}}\]

    Correct Answer: A

    Solution :

                    \[E=\frac{1}{2}L{{i}^{2}}\] hence \[L=[M{{L}^{2}}{{T}^{-2}}{{A}^{-2}}]\]
