A capacitor stores electrical energy in what kind of field?

Explanation:
When a capacitor is charged, separated charges on its plates create an electric field in the dielectric between them. The energy stored in a capacitor comes from this electric field, and when the charges are stationary (no changing current), that field is electrostatic. This distinguishes it from magnetic energy (stored in magnetic fields around current-carrying conductors) and from electromagnetic energy (in time-varying fields or radiation). So the stored energy in a charged capacitor resides in the electrostatic field between the plates.
