Suppose a battery is connected to a parallel-plate capacitor with (infinitely) large plates and capacitance C, and the battery charges it up to a potential difference AV. Then the battery is disconnected and the spacing between the capacitor plates is doubled. The spacing is still smaller than the diameter of the plates. What is the change in each of the following? the volume ....... the electric field between the plates .. the electric potential difference between the plates.. the energy stored ....... the capacitance.. Answer each question with "increases", "decreases" or "stays the same".
