    What is the coefficient of mutual inductance when the magnetic flux changes by \[3\times {{10}^{-2}}\]wb and change in the current is \[0.01\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]?            

    A)              8H                                             

    B)              6 H            

    C)                     3 H            

    D)                                    1.5 K

    Correct Answer: C

    Solution :

    Here: change in magnetic flux \[\phi =3\times {{10}^{-2}}wb\] Change in current = 0.01 A Change in magnetic flux \[\phi =3\times {{10}^{2}}=MI\] \[3\times {{10}^{-2}}=M\times I\] \[M=\frac{3\times {{10}^{-2}}}{0.01}=3H\]
