oltage across the inductor in the circuit is proportional to the rate of current flow through the inductor. For this first calculate the current flowing through the branch containing L and R2. Then differentiate current i with respect to time t.
An inductor of inductance L= 400mH and resistors R1=2Ω and R2=2Ω are connected to a battery of emf 12V . The internal resistance of the battery is negligible. The switch S is closed at t=0. The potential drop across L as a function of time is:
