- Clausius-Mossotti relation [r]: connects the relative permittivity εr of a dielectric to the polarizability α of the atoms or molecules constituting the dielectric. [e]
- Coulomb's law [r]: An inverse-square distance law, like Newton's gravitational law, describing the forces acting between electric point charges; also valid for the force between magnetic poles. [e]
- Dielectric [r]: an insulating, but polarizable, material that can be solid, liquid or gas; its important characterizing property is the relative permittivity (aka dielectric constant). [e]

- Electricity [r]: The flow or presence of electric charge; the flow of electricity is an important carrier of energy. [e]
- Electromagnetic wave [r]: A change, periodic in space and time, of an electric field E(r,t) and a magnetic field B(r,t); a stream of electromagnetic waves, referred to as electromagnetic radiation, can be seen as a stream of massless elementary particles, named photons. [e]
