Capacitance and Charge. Capacitors store electrical energy on their plates in the form of an electrical charge. Capacitance is the measured value of the ability of a capacitor to store an electric charge. This capacitance value also depends on the dielectric constant of the dielectric material used to separate the two parallel plates.

When a 360-nF air capacitor is connected to a power supply, the energy stored in the capacitor is 18.5μJ. While the capacitor is connected to the power supply, a slab of dielectric is inserted that completely fills the space between the plates. This increases the.
Conversely, when the voltage across a capacitor is decreased, the capacitor supplies current to the rest of the circuit, acting as a power source. In this condition the capacitor is said to be discharging. Its store of energy—held in the electric field—is decreasing
The action of a capacitor. Capacitors store charge and energy.

During charging electrons flow from the negative terminal of the power supply to one plate of the capacitor and from the other plate to the positive terminal of the power supply. When the switch is closed, and charging starts, the rate of flow of charge is large (i.e. a big current) and this decreases as time goes by and the plates become more charged so …
A capacitor is made up of two conductive plates, which are separated by an insulating material called a dielectric. The plates are usually made out of materials like aluminium and copper, and the dielectric can be made out of materials like ceramic, plastic and paper.
