In electromagnetism, absolute permittivity is the measure of the resistance that is encountered when forming an electric field in a medium. In other words, permittivity is a measure of how an electric field affects, and is affected by, a dielectric medium. The permittivity of a medium describes how much electric field (more correctly, flux) is `g....

the proportionality constant between the dielectric displacement D and the electric field E.
(e) The ratio of the electric displacement in a medium to the intensity of the electric field producing it. It is important for electrical insulators used as dielectrics. If two charges q1 and q2 are separated by a distance...
the proportionality constant between the dielectric displacement D and the electric field E.
Dielectric Constant. The transport and road research laboratory have shown that the ability of bitumen to weather under the combined effects of oxygen, rain and oil deposition from traffic and ultra-violet light in sunlight is related to the dielectric constant of the bitumen.
preferred term for dielectric constant. It is that property of a dielectic material that determined how much electrostatic energy can be stored per unit of volume when unit voltage is applied; the relative permittivity of most materials varies from 2 to 10, air having 1.
