(credit: Kucharek, Wikimedia Commons) Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q Q and voltage V V on the capacitor.

Energy Stores

The temperature of a body (object) is a measure of the energy in the kinetic stores of its particles. Increasing a body''s temperature increases the energy in the kinetic stores of the body''s particles, which means that the energy in the body''s internal store also increases.

How can energy be stored in a field?

6. Energy stored in fields = the total energy required to assemble the fields. It takes energy to bring the charges to specific positions to assemble the field, and when you let everything go, the charges will just fly apart. The energy you stored in the field becomes the kinetic energy of the charges once you let them go.

Energy of a capacitor (video) | Khan Academy

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 necessarily the battery ...
