Self Induction

Series RC and RL circuit

The role of self-inductance in a circuit is equivalent to :

Assertion: Inductive reactance of an inductor in DC circuit is zero. Reason: Angular frequency of DC circuit is zero.

The inductors of the two LR circuits are placed next to each other , as shown in the figure . The values of the self-inductance of the inductors , resistances , mutual - inductance and applied voltages are specified in the given circuit . After both the switches are closed simultaneously , the total work done by the batteries against the induced EMF in the inductors by the time the currents react their steady state values is __________m]
