Question

Figure shows a circuit that contains three identical resistors with resistance R = 9.0 Ω each, two identical inductors with inductance ε = 2.0 mH each, and an ideal battery with emf e = 18 V. The current 'i' through the battery just after the switch closed is,...... :-

Options

A.

0.2 A

B.

2 A

C.

0 ampere

D.

2 mA

Solution


at t = 0
i1 =εR=189=2A
Current through the battery is
i = 2i1 = 2 × 2 = 4A (Bonus)
   OR
According to question language :
Capacitor is not mentioned so i = 2 A
