Q. In the figure shown, the capacity of the condenser $C$ is $2\ \mu F.$ The current in $2\Omega$ resistor is
A) $9\ A$
B) $0.9\ A$
C) $\frac{1}{9}A$
D) $\frac{1}{0.9}A$
Explanation
(b) No current flows through the capacitor branch in steady state. Total current supplied by the battery
$i = \frac{6}{2.8 + 1.2} = \frac{3}{2}$
Current through $2\ \Omega$ resistor $= \frac{3}{2} \times \frac{3}{5} = 0.9A$
