What is a Capacitor? A capacitor is a two-terminal passive electrical component that can store electrical energy in an electric field.This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit.

The mobile capacitor banks is a packaged factory assembled and tested reactive compensation system with modular fixed or switched capacitor steps, which automatically compensate an individual load or the network to maintain a preset level of power factor.
Inductors. Inductors work by creating and using magnetic fields to store energy and resist changes in electric current. They''re like energy storage devices, but instead of storing electrical energy directly like a battery or a capacitor, they store energy in a magnetic field created by the current flowing through a coil of wire.
Unlike a battery which stores energy and then gradually releases it, capacitors can be discharged in an instant. A basic unit consists of two conductors, or electrodes, separated from one another by an insulator, or dielectric. ...

This energy is saved in potential energy form since at any time, once the circuit is closed, the coulomb force can finally push out the excess electrons, thus increasing their kinetic energy again. It really does resemble a spring a lot, just that the "force trying to push things out" is now electromagnetic instead of the usual spring force.

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 charge in moving it from one plate to the other would appear as energy stored. But in fact, the expression above shows that just half of that work appears as energy stored in the capacitor.
