Question

A network of resistances, cell and capacitor $C( = 2 \,\mu F)$ is shown in adjoining figure. In steady state condition, the charge on $2 \,\mu F$capacitor is $Q$, while $R$ is unknown resistance. Values of $Q$ and $R$ are respectively

• A. $4 \,\mu C$ and $10 \,\Omega$
• B. $4 \,\mu C$ and $4 \,\Omega$
• C. $2 \,\mu C$ and $2 \,\Omega$
• D. $8 \,\mu C$ and $4 \,\Omega$

Answer 1

Answer: (A)

$4 \,\mu C$ and $10 \,\Omega$

Answer 2

In the steady state, no current will flow through capacitor.
