Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. …

A capacitor is a device that stores electrical charge. The simplest capacitor is the parallel plates capacitor, which holds two opposite charges that create a uniform electric field between the plates. Therefore, the energy in a capacitor comes from the potential difference between the charges on its plates.
