A capacitor is a two-terminal electrical device that stores energy in the form of an electric charge. A capacitor is made up of 2 electrical conductors separated by distance. Capacitors are also called electric condensers. The space between these conductors might also be filled with a vacuum or an insulating material that is called a dielectric.

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 on the conductors.
In electrical electronics, the component used to store electrical energy in an electric field is known as a "Capacitor". It is a passive device that can store an electrical charge on its plates when connected to a voltage source. Capacitors contain two-terminal and their effect is known as capacitance.
