In the connection shown in the figure the switch K is open and the capacitor is uncharged. Then we close the switch and let the capacitor charge upto the maximum and open the switch again.

Question

TestHub · Accepted Answer

After K is closed the capacitor charges through $R_{2}$ and the galvanometer, the current decaying to zero at full charge, so the reading rises then falls - (A) correct.

Opening K again, the capacitor discharges through the $R_{2}$ -G loop in the same direction through the galvanometer - (B) correct.

With K open no current flows through $R_{1}$ , so dissipation in $R_{1}$ is zero - (C) correct; the discharge current dissipates energy in $R_{2}$ , so (D) is wrong.
