1. An inductor coil stores 32 J of magnetic field energy and dissipates energy as heat at the rate of 320 W when a current of 4 A is passed through it. Find the time constant of the circuit when this coil is joined across an ideal battery. 2. Coils A and B have mutual inductance 25 mH. At time t=0 the current in coil A is zero- Subsequently a time-varying current is supplied to A, and the induced emf in coil B is given by E=0.5 +0.21, with Ein Volts and t in seconds. Find an expression for the time varying current in coil A and then find the current at tals:
