8.2: Capacitors and Capacitance
The capacitance C C of a capacitor is defined as the ratio of the maximum charge Q Q that can be stored in a capacitor to the applied voltage V V across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device: C = Q V (8.2.1) (8.2.1) C = Q V.

Energy of a capacitor (video) | Khan Academy
About. Transcript. Capacitors store energy as electrical potential. When charged, a capacitor''s energy is 1/2 Q times V, not Q times V, because charges drop through less voltage over time. The energy can also be expressed as 1/2 times capacitance times voltage squared. Remember, the voltage refers to the voltage across the capacitor, not ...
