    An e.m.f. of 12 volt is produced in a coil when the current in it changes at the rate of 45 amp/minute. The inductance of the coil is                                                                   [MP PET 2000]

    A)            0.25 henry                             

    B)            1.5 henry

    C)            9.6 henry                               

    D)            16.0 henry

    Correct Answer: D

    Solution :

               \[e=L\frac{di}{dt}\Rightarrow 12=L\times \frac{45}{60}\Rightarrow L=16H\]
