Related to Electrical permittivity: dielectric constant


n. pl. per·mit·tiv·i·ties
A measure of the ability of a material to interact with an electric field and become polarized by the field, so that the field within the material is weaker than the field in the absence of the material. The permittivity of a material is the product of the dielectric constant of the material and the permittivity of a perfect vacuum, which is defined to be about 8.854 × 10-12 farad per meter.


n, pl -ties
(General Physics) a measure of the response of a substance to an electric field, expressed as the ratio of its electric displacement to the applied field strength; measured in farads per metre. Symbol: ε See also relative permittivity, electric constant


(ˌpɜr mɪˈtɪv ɪ ti)

n., pl. -ties.
the ratio of the flux density produced by an electric field in a given dielectric to the flux density produced by that field in a vacuum.
