A battery of e.m.f. V volts, resistors R1 and R2, a condenser C and switches S1 and S2 are connected in the circuit as shown in the figure below :
The condenser will get fully charged to V volts when -
A
S1 and S2 are both closed
B
S1 and S2 are both open
C
S1 is open and S2 is closed
D
S1 is closed and S2 is open
Answer
S1 is closed and S2 is open
Explanation
Solution
S1 (closed) charges the capacitor
S2 (closed) discharges the capacitor
∴ To charge the capacitor
S1 → closed, S2 → opened
