Question:
Figure shows a circuit that contains four identical resistors with resistance $\mathrm{R}=2.0 \Omega$. TWo identical inductors with
inductance $\mathrm{L}=2.0 \mathrm{mH}$ and an ideal battery with emf $\mathrm{E}=9$. V. The current 'i' just after the switch 's' is closed will be :
Correct Option: , 3
Solution:
(3)
When switch $S$ is closed-
Given : $v=9 v$
From $V=I R$
$I=\frac{V}{R}$
$R_{\mathrm{eq} .}=2+2=4 \Omega$
$I=\frac{9}{4}=2.25 \mathrm{~A}$
