What a capacitor does

What a capacitor does

Parallel-plate capacitor with labelled positive and negative plates, dielectric, electric field lines, plate separation, and potential difference A capacitor stores separated charge on two conductors and stores energy in the electric field between them. It does not store current, and the insulating material between the plates is called the dielectric.
