A 12.5 μF capacitor is connected to a power supply that keeps a constant potential difference of 26.0 V across the plates. A piece of material having a dielectric constant of 3.90 is placed between the plates, completely filling the space between them. a) How much energy is stored in the capacitor before the dielectric is inserted? b) How much energy is stored in the capacitor after the dielectric is inserted? c) By how much did the energy change during the insertion?
