    The dimensions of emf in MKS is

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

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

    C) \[ML{{T}^{-2}}{{Q}^{-1}}\]             

    D) \[M{{L}^{2}}{{T}^{-2}}{{Q}^{-1}}\]   

    Correct Answer: D

    Solution :

    \[e=L\frac{di}{dt}\Rightarrow [e]=[M{{L}^{2}}{{T}^{-2}}{{A}^{-2}}]\left[ \frac{A}{T} \right]\] \[[e]=\left[ \frac{M{{L}^{2}}{{T}^{-2}}}{AT} \right]=[M{{L}^{2}}{{T}^{-2}}{{Q}^{-1}}]\]
