    If a current of 10 A flows in one second through a coil and the induced emf is 10V, then the self-inductance of the coil will be

    A) 1 H         

    B)                        2 H                         

    C) 4 H                         

    D)        \[\frac{2}{5}H\]

    Correct Answer: A

    Solution :

    The induced emf is given by \[e=L\frac{di}{dt}=L\times \frac{10}{1}\] or            \[10=10\,L\] Hence, \[L=1H\]
