- Born-Oppenheimer approximation : A technique in quantum mechanics in which the kinetic energies of nuclei and electrons are calculated separately.
- Clausius-Mossotti relation : connects the relative permittivity εr of a dielectric to the polarizability α of the atoms or molecules constituting the dielectric.
- Coulomb's law : 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.
- Electric displacement : a vector field D in a dielectric; D is proportional to the outer electric field E.
- Electric field : force acting on an electric charge—a vector field.
- Electricity : The flow or presence of electric charge; the flow of electricity is an important carrier of energy.
- Electromagnetic wave : 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.
- Farad : SI unit of capacitance; symbol F: 1 F = 1 C/V
- Gauss' law (electrostatics) : Relates the surface integral of the electric displacement through a closed surface to the electric charge enveloped by the closed surface.
- Gauss' law (magnetism) : States that the total magnetic flux through a closed surface is zero; this means that magnetic monopoles do not exist.
- Gaussian units : A centimeter-gram-second system of units often used in electrodynamics and special relativity.
- Green's function : Auxiliary function in the theory of linear differential equations; integral operator with Green function as kernel is the inverse of a linear differential operator.
- Lorentz-Lorenz relation : An equation describing the relation between the density and index of refraction of a dielectric.
- Magnetic constant : A physical constant in the International System of Units (SI) relating mechanical force and electric current in classical vacuum with a defined value μ0 = 4π × 10−7 N/A2.
- Maxwell equations : Mathematical equations describing the interrelationship between electric and magnetic fields; dependence of the fields on electric charge- and current- densities.
- Momentum : mass of a particle times its velocity (a vector).
- Polarizability : The ease by which a charge-distribution polarizes; describes the amount of charge separation caused by an electric field.
- Relative permittivity : A factor describing the polarizability of a material or medium as a proportionality between an electric displacement and an electric field in a dielectric.
- Speed of light : A physical constant c describing the speed of electromagnetic radiation in vacuum. In the International System of Units the metre is the distance light travels in classical vacuum in 1/c seconds, using the defined value c = c0 ≡ 299 792 458 m/s (exact).
- Statcoulomb : Unit of electric charge in cgs-esu units: 1 statC = C/(10⋅c), with c the speed of light in m/s.
