= 12 V Problem 19.07. A capacitor with capacitance C = 4.75 µF is charged with a V battery then disconnected from the battery. (a) Calculate the charge stored on the capacitor. (b) Calculate the energy stored in the capacitor. If the dielectric material in the capacitor with K = 3.25 is removed and the separation is changed from d = 100 mm to d = 500 μm, what is the voltage across the capacitor? (d) How much energy was lost or gained in the system by rearranging the capacitor?
