When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material. Instead, electric polarization occurs.

The study of dielectric properties concerns storage and dissipation of electric and magnetic energy in materials. See more In electromagnetism, a dielectric (or dielectric medium) is an electrical insulator that can be polarised by an applied electric field. When a dielectric material is placed in an electric field, electric charges do not flow through the … See more The electric susceptibility χe of a dielectric material is a measure of how easily it polarises in response to an electric field. This, in turn, determines the electric permittivity of … See more In physics, dielectric dispersion is the dependence of the permittivity of a dielectric material on the frequency of an applied electric field. Because there is a lag between changes in polarisation and changes in the electric field, the permittivity of the … See more Paraelectricity is the nominal behaviour of dielectrics when the dielectric permittivity tensor is proportional to the unit matrix, i.e., an applied electric field causes polarisation and/or … See more Although the term insulator implies low electrical conduction, dielectric typically means materials with a high polarisability. The latter is … See more Basic atomic model In the classical approach to the dielectric, the material is made up of atoms. Each atom consists of a cloud of negative charge (electrons) bound to and surrounding a positive point charge at its center. In the … See more Dielectric relaxation is the momentary delay (or lag) in the dielectric constant of a material. This is usually caused by the delay in molecular polarisation with respect to a changing electric field in a dielectric medium (e.g., inside capacitors or between two large See more taylor colebank alltrailsWebThe dielectric strength of a material is the maximum voltage required to produce electrical breakdown in that material.
