    If a current of 10 A flows in one second through a coil, and the induced e.m.f. is 10 V, then the self-inductance of the coil is      [CPMT 2000; Pb. PMT 2001; MHCET 2003]

    A)            \[\frac{2}{5}H\]                   

    B)            \[\frac{4}{5}H\]

    C)            \[\frac{5}{4}H\]                   

    D)            1 H

    Correct Answer: D

    Solution :

               \[|e|\,=L\frac{di}{dt}\Rightarrow 10=L\times \frac{10}{1}\Rightarrow L=1H\]
