This maximum voltage depends the dielectric in the capacitor. The corresponding maximum field E b is called the dielectric strength of the material. For stronger fields, the capacitor ''breaks down'' (similar to a corona discharge) and is normally destroyed. Most capacitors used in electrical circuits carry both a capacitance and a voltage rating.

With the electric field thus weakened, the voltage difference between the two sides of the capacitor is smaller, so it becomes easier to put more charge on the capacitor. Placing a dielectric in a capacitor before charging it therefore allows more charge and potential energy to be stored in the capacitor.
