An initially uncharged parallel plate capacitor of capacitance C is charged to potential V by a battery. The battery is then disconnected. Which statement is correct?
A) There is no charge on either plate of the capacitor.
B) The capacitor can be discharged by grounding any one of its two plates.
C) Charge is distributed evenly over both the inner and outer surfaces of the plates.
D) The magnitude of the electric field outside the space between the plates is approximately zero.
E) The capacitance increases when the distance between the plates increases.

Question

Quizplus · Accepted Answer

When the battery is disconnected, the charge remains on the plates, creating an electric field between them. Outside this region, the field is approximately zero due to the cancellation of fields from the two plates.
