    The value of current in primary coil is

    A) \[0\centerdot 125A\]

    B) \[2\centerdot 52A\]

    C) \[1\centerdot 51A\]

    D) \[3\centerdot 52A\]

    Correct Answer: A

    Solution :

    As \[\frac{{{I}_{p}}}{{{I}_{s}}}=\frac{{{E}_{s}}}{{{E}_{p}}}\] \[\Rightarrow \,\,{{I}_{p}}=\frac{{{E}_{s}}}{{{E}_{p}}}\times {{I}_{s}}=\frac{3}{120}\times 5=0.125\,A\]
