> as lemmasdielectric constant dielectric constant n. one of the physical parameters of a non-conducting medium, equal to the ratio of the electric displacement at any point in the medium to the displacement an identical charge distribution would produce in a vacuum, measured at the same point; the relative permittivity. (Some writers call this the relative dielectric constant, using dielectric constant for the ratio of electric displacement to electric field strength: cf. permittivity n.)< |
