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

Correct answer: C. 2A

When the switch is just closed, the inductors show infinite opposition and hence both the branches with Inductor-Resistor combination do not really participate in the circuit.

Figure shows a circuit contains three identical resistors with resistance R = 9.0Ω each, two identical inductors with

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

At $t = 0$ inductor behaves like an open wire.

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