S R1 w E = C R2 A circuit contains an ideal battery with potential difference E, two resistors with resistances R1 and R2, a capacitor of capacitance C, and switch S, as shown. The switch is closed. A long time after the switch is closed, the positive plate of the capacitor has charge +Q. What change to the circuit can a student make to increase the amount of charge stored on the positive plate of the capacitor? A Replace R with a new resistor of larger resistance. B Replace R, with a new resistor of larger resistance. с Replace the capacitor with a capacitor that is identical except that there is more separation between its plates. D Replace the capacitor with a capacitor that is identical except that the plates have a smaller area. E Replace the battery with an ideal battery that has a lower potential difference.
