In the figure shown, a circuit contains two identical resistors with resistance R = 5 Ω and an inductance with L = 2 m H . An ideal battery of 15 V is connected in the circuit. What will be the current through the battery long after the switch is closed?

Question

In the figure shown, a circuit contains two identical resistors with resistance R = 5 Ω and an inductance with L = 2 m H . An ideal battery of 15 V is connected in the circuit. What will be the current through the battery long after the switch is closed?, 5.5 A, 6 A, 3 A, 7.5 A

MARKS App · Accepted Answer

After a long time, when the growth of current in the circuit has stopped, the inductor will work as a conductor. Therefore the effective resistance of the circuit will be, R = 5 2 = 2 . 5 Ω Hence, the current through the circuit will be, I = V R = 15 2.5 = 6 A
