Question
Figure shows a circuit that contains three identical resistors with resistance R = 9.0 each, two identical inductors with inductance = 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
Current through the battery is
i = 2i1 = 2 2 = 4A (Bonus)
OR
According to question language :
Capacitor is not mentioned so i = 2 A
