Question

A battery of emf $V\text{volt}$, resistance $R_1$ and $R_2$, a capacitance $C$ and switches $S_1$ and $S_2$ are connected in an electrical circuit as shown in figure. The capacitor $C$ gets fully charged to $V\text{volt}$ when -

• A. $S_1$ and $S_2$ are both closed
• B. $S_1$ and $S_2$ are both open
• C. $S_1$ closed and $S_2$ open
• D. $S_2$ closed and $S_1$ open

Answer 1

The correct option is C $S_1$ closed and $S_2$ open

The capacitor $C$ get fully charged to $V\text{volts}$ when $S_1$ is closed but $S_2$ is open. When $S_1$ will be closed, the capacitor will get connected in series with the circuit.
