The energy (U_C) stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates.

The greater the difference of electrons on opposing plates of a capacitor, the greater the field flux, and the greater the "charge" of energy the capacitor will store. Because capacitors store the potential energy of accumulated electrons in the form of an electric field, they behave quite differently than resistors (which simply dissipate energy in the …
18.5 Capacitors and Dielectrics
Notice that the electric-field lines in the capacitor with the dielectric are spaced farther apart than the electric-field lines in the capacitor with no dielectric. This means that the electric field in the dielectric is weaker, so it stores less electrical potential energy than the electric field in the capacitor with no dielectric.
5.16: Inserting a Dielectric into a Capacitor
This produces an electric field opposite to the direction of the imposed field, and thus the total electric field is somewhat reduced. Before introduction of the dielectric material, the energy stored in the capacitor was (dfrac{1}{2}QV_1). After introduction of the

Energy Stored on a Capacitor
From the definition of voltage as the energy per unit charge, one might expect that the energy stored on this ideal capacitor would be just QV. That is, all the work done on the …
A Complete Guide to Capacitors
A capacitor is an electrical component used to store energy in an electric field. It has two electrical conductors separated by a dielectric material that both accumulate charge when connected to a …
Energy Stored in a Capacitor | Brilliant Math & Science Wiki
A capacitor is a device for storing energy. When we connect a battery across the two plates of a capacitor, the current charges the capacitor, leading to an accumulation of charges …

Energy of a capacitor and an electric field
Electric field is constant in any point of space, forces affecting the charges +q and –q, are equal with an opposite sign. Resulting force is 0. The dipole of these forces is not 0, if the dipole is not oriented parallel to the electric field …
Capacitor in Electronics
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …

Field energy
Field energy. When a battery charges a parallel-plate capacitor, the battery does work separating the charges. If the battery has moved a total amount of charge Q by moving electrons from the positively charged plate to the negatively charged plate, then the voltage across the capacitor is V = Q/C and the amount of work done by the battery is W = ½CV 2.
