    Two circuits have mutual inductance of 0.1 H. What average emf is induced in one circuit when the current in the other circuit changes from 0 to 20 A in 0.02s?

    A)  240 V          

    B)  230 V

    C)  100 V          

    D)  300 V

    Correct Answer: C

    Solution :

    \[e=M\times \frac{dI}{dt}\] \[=0.1\times \frac{(20-0)}{0.02}=100\,V\]
