Question

An inductor of inductance L = 400mH and resistors of resistances R₁ = 2Ω and R₂ = 2Ω are connected to a battery of emf 12V as shown in the figure. 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

Answer 1

(d) : For the given R, L circuit the potential difference across AD = VBC as they are parallel.
