Question
Find the current passing through battery immediately after key $(K)$ is closed. It is given that initially all the capacitors are uncharged......$A$ (Given that $R = 6\,\Omega$ and $C = 4\, \mu F$)



$R_{n e t}=\frac{R}{2}+\frac{R}{3}=\frac{5 R}{6}=5 \Omega$
$\therefore$ Current from the battery,
$i=\frac{E}{R_{n e t}}=\frac{5}{5}=1 A$
