ElectroMagnetic InductionHard
Question
A closed circuit consists of a source of constant emf E and a choke coil of inductance L connected in series. The active resistance of the whole circuit is equal to R. It is in steady state. At the moment t = 0 the choke coil inductance was decreased abruptly h times. Find the current in the circuit as a function of time t.
