Dielectric constant

Definition

The dielectric constant, also known as the relative permittivity, is a measure of how well a material can store electrical energy in an electric field. It quantifies the ability of a material to polarize in response to an applied electric field.

Related terms

Electric susceptibility: This term refers to the extent to which a material can become polarized when subjected to an external electric field.

Permittivity: Permittivity is a measure of how easily electric fields can penetrate through a material. It is related to the dielectric constant but takes into account other factors such as free charges.

Capacitance:

Capacitance is a property that describes how much charge can be stored on an object per unit voltage. It depends on both the geometry and dielectric constant of the medium between two conductors.
