Question

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. $\frac{1}{0.9} A$

Answer 1

Answer: (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
$=\frac{3}{2} \times \frac{3}{5}=0.9\, A$
