The current in the primary of a transformer drops from 5 to 3 A in 2 s. If the mutual inductance between the two coils is 0.16 H, then calculate the induced emf in the secondary.

The mutual inductance between two coils is 0.15 H. If a current of 20 A in the primary coil is cut off in 0.05 s, find the emf induced in the secondary coil. If the secondary coil has 60 turns, then find the flux-change in it.
