An inductor (solenoid) with inductance, L = 0.5 H and negligible resistance, a battery, an S Switch, R1 = 20 k. ohm R2 = 15 k.it is connected to two resistance such as ohm as shown in the figure. The battery's EMC is 122 V and its resistance is negligible. The S Switch turns off AT t=0. at what time does the i3 current reach a third of its final value, which it will achieve after the Switch is turned off for a long time?
