    \[62.5\times {{10}^{18}}\] electrons per second are flowing through a wire of area of cross-section 0.1\[{{m}^{2}}\], the value of current flowing will be                                                                          [CPMT 1984]

    A)                    1 A

    B)                                      0.1 A

    C)                    10 A

    D)                    0.11 A

    Correct Answer: C

    Solution :

                 \[i=\frac{ne}{t}=\frac{62.5\times {{10}^{18}}\times 1.6\times {{10}^{-19}}}{1}=10\,ampere\]
