A parallel plate capacitor with an air dielectric is attached to a voltage source and charged.The voltage source is removed,and then the plates are separated to double their previous distance.What happens to the potential difference between the plates when they are separated?

Question

Quizplus · Accepted Answer

When the plates of a capacitor are separated, the capacitance decreases. Since the charge remains constant (as the voltage source is removed), the potential difference increases. Specifically, if the distance between the plates is doubled, the potential difference also doubles.
