    Find out the e.m.f. produced when the current changes from 0 to 1 A in 10 second, given L = 10 mH          [DCE 2001]

    A)            1 V

    B)            1 mV

    C)            1 mV                                        

    D)            0.1 V

    Correct Answer: B

    Solution :

               \[|e|\,=L\frac{di}{dt}\Rightarrow \,|e|\,=10\times {{10}^{-6}}\times \frac{1}{10}=1\mu V\]
