In the circuit arrangement, shown in fig, initially both the switches S1 and S2 are open. At t = 0, the switch S1 is closed and at t = t0 , the switch S2 is also closed when the current in L1 has become i1 = 0.756 A. At t = t0, the magnitude of current i2 and rate of change of current

di2

d

are given by : (i2 is the current in L2)
