    Dimension of electric current is                        [CBSE PMT 2000]

    A)             \[[{{M}^{0}}{{L}^{0}}{{T}^{-1}}Q]\]           

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

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

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

    Correct Answer: A

    Solution :

                    \[I=\frac{Q}{t}=\frac{[Q]}{[T]}=[{{M}^{0}}{{L}^{0}}{{T}^{-1}}Q]\]
