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 electric field between the plates when they are separated?

Question

Quizplus · Accepted Answer

The electric field between the plates of a capacitor is determined by the charge on the plates and the area of the plates, not the distance between them. Once the voltage source is removed, the charge remains constant, so the electric field stays the same.
