Question 190 of 190

The figure shows a circuit that contains four identical resistors with resistance $R=2.0\Omega ,$ two identical inductors with inductance $L=2.0mH$ and an ideal battery with E.M.F. $E=9V.$ The current $i$ just after the switch $S$ is closed will be:

A$9A$B$3.37A$C$2.25A$D$3.0A$

Show answer and solution▾

Answer: (C) $2.25A$

Just after the switch is closed, inductor will behave like infinite resistance (open circuit) so the circuit will look like

$i=\dfrac{9}{R+R}=\dfrac{9}{4}=2.25A$
