A parallel-plate capacitor is connected to a battery that maintains potential difference V between the plates. If the plates of the capacitor are pulled farther apart, do the following quantities increase, decrease, or remain the same?
(a) Electric field between the plates;
(b) charge on the plates;
(d) energy stored in the capacitor.
In all these cases the battery is maintaining a constant voltage V. Increasing d decreases the capacitance as C = epsilon o A/d and epsilon o and A remain the same while d increases.
(a) Electric field between the plates ...
