# Figure shows a circuit contains three identical resistors with resistance R = 9.0  each, two identical inductors with inductance L = 2.0 mH each, and an ideal battery with emf = 18 V. The current 'i' through the battery just after the switch closed is, ... Option 1) 2 mA Option 2) 0.2 A Option 3) 2 A Option 4) 0 ampere

As we learnt in

RLC circuit Voltage -

$V_{R}=iR\: \: \: V_{L}= {i}\ X_{L}\: \: \: V_{C}={i}\ X_{C}$

- wherein

At t=0, no current flows through  R1 and R3

Current through battery just after the switch closed is

$1^{1}= \frac{\varepsilon }{9}=\frac{18}{9}=2A$

Option 1)

2 mA

This option is incorrect

Option 2)

0.2 A

This option is incorrect

Option 3)

2 A

This option is correct

Option 4)

0 ampere

This option is incorrect
