Two rectangular parallel plates have area A and are separated by a distance d. They are connected to a power supply and charged with a voltage V. There no insulating material between them. In this configuration the plates make a capacitor with capacitance C. The electric field between the plates is E and the energy stored is U While still connected to the power supply, the plates are moved so the distance between them is one-half what it was. By...
