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

i=(ε/R2) =(18/9) =2 A

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

0.2 A

2 A

0 ampere

2 mA

At $t = 0$ , no current flows through $R_{1}$ and $R_{3}$

$i = \frac{ε}{R _{2}}$
$= \frac{18}{9}$
$= 2 A$
