Figure shows a circuit that contains three identical resistors with resistance R = 9.0 Ω each, two identical inductors with inductance L = 2.0 mH each, and an ideal battery with emf ε = 18 V. The current 'i' through the battery just after the switch closed is
-
- 0.2 A
- 2 A
- 0
- 2 mA
Correct Option: B
At t = 0, no current flows through R1 and R3
Current through battery just after the switch closed is
i - | ε | = | 18 | = 2 A |
R2 | 9 |
