A 13.0 uF capacitor is connected to a powersupply that keeps a constant potential dilference of24.0 V across the plates. A piece of materlal havinga dielectric constant of 3.80 is

placed between theplates, completely filling the space between lhem. Part AHow much energy is stored in the capacitor before the dielectric is inserted? Part BHow much energy is stored in the capacitor after the dielectric is inserted? Part CBy how much did the enorgy change during the insertion?
