• question_answer1)  An inductor of inductance\[L=400\text{ }mH\]and resistors of resistances\[{{R}_{1}}=2\text{ }\Omega \]and \[{{R}_{2}}=2\Omega \]are connected to a battery of emf 12 V 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:     AIEEE  Solved  Paper-2009
