The current flowing in the first coil changes from 2A to 10A in 0.4 sec. Find the mutual inductance between two coils if an EMF of 60mV is induced in the secondary coil.also determine the induced EMF in the secondary coil if the current in the first coil is changed from 4A to 16A in 0.03 sec.

Answer:
mutual inductance=3m H
v1/v2=i2/i1
v1=60m V×8/12=40m V
