JEE Mains Model Paper 6

An inductor of inductance L = 400 mH and resistors of resistances R1 = 2 Ω and R2 = 2 Ω areconnected to a battery of emf 12 V as shown in the figure. The internal resistance of the battery isnegligible. The switch S is closed at t = 0. The potential drop across L as a function of time is
