The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field. Permittivity is a material's property that affects the Coulomb force between two … WebJun 1, 2015 · Al 2 O 3 { aluminum oxide, alumina } Key to the Symbols: T = temperature, d = density, p = volume fraction of porosity, VL = longitudinal sound velocity, VS = shear … chemin d\\u0027hydra el biar gym nearby
