Permittivity of bakelite
WebFeb 15, 2024 · In the centimetre-gram-second system, the dielectric constant is identical to the permittivity. It denotes a large-scale property of dielectrics without specifying the electrical behaviour on the atomic scale. The value of the static dielectric constant of any material is always greater than one, its value for a vacuum. WebFeb 2, 2011 · The absolute permittivity of a dielectric is therefore Values of relative permittivity of common insulating materials are in the range 2-10 (e.g., bakelite, 4.5-5.5; …
