One of the physical parameters of a medium, determining its ability to store electrical energy in an electric field, and equal to the ratio of the electric flux density to the electric field strength at any point.
Is the measure of the ability of a material to store electrical energy when exposed to an electrical field.
A measure of the degree to which a medium can resist the flow of electric charge.
A property of material that indicates how much polarization occurs when an electric field is applied. Complex permittivity is a property that describes both polarization and absorption of energy. The real part is related to polarization; the imaginary part, to energy absorption.
the proportionality constant between the dielectric displacement D and the electric field E.
see dielectric permittivity.
That property of dielectric that determines the electrostatic energy stored per unit volume for a unit potential gradient braided, or taped (longitudinally or spirally).(2) In cables, a metallic layer placed around a conductor or group of conductors to prevent electrostatic or electromagnetic interference between the enclosed wires and external fields.
preferred term for dielectric constant. It is that property of a dielectric material that determines 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.
The property which enables a three-dimensional material to store electrical ge; i.e. its capacitivity.
n. the ratio of electric flux density produced by an electric field in a medium to that produced in a vacuum by the same field
Permittivity is a physical quantity that describes how an electric field affects and is affected by a dielectric medium, and is determined by the ability of a material to polarize in response to the field, and thereby reduce the field inside the material. Thus, permittivity relates to a material's ability to transmit (or "permit") an electric field.
