Figure (PageIndex{1}): Energy stored in the large capacitor is used to preserve the memory of an electronic calculator when its batteries are charged. (credit: Kucharek, Wikimedia Commons) Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge (Q) and voltage (V) on the capacitor.
If a capacitor is charged by putting a voltage V across it for example, by connecting it to a battery with voltage V—the electrical potential energy stored in the capacitor is U E = 1 2 C V 2 . U E = 1 2 C V 2 .
