Q1:

The diagram shows a circuit containing a capacitor, a resistor, and a switch connected in series. The capacitor is initially fully charged, and the switch is initially open. Immediately after the switch is closed, the current through the circuit is 0.2 A. What was the potential difference across the capacitor when it was fully charged?

Q2:

A capacitor is connected to a cell and allowed to fully charge. What is the potential difference across the capacitor once it has fully charged?

Q3:
