P.No.15.6:- A pair of adjacent coils has a mutual inductance of 0.75H. If the current in the primary changes from 0 to 10A in 0.025s, what is the average induced emf in the secondary? What is the change in flux in it if the secondary has 500 turns?

Solution:-

Given Data:-

            Mutual inductance                             =     M      =   0.75H
