what is dielectric constant or relative permittivity.?
Answers
Answer:
The dielectric constant - also called the relative permittivity indicates how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of "thepermittivity of a substance to the permittivity of space or vacuum".
Answer:
The dielectric constant or relative permittivity or specific inductive capacity or dielectric coefficient is given by the ratio of the absolute permittivity of the medium to the permittivity of free space.
K = εr = ε/ε0
The dielectric constant or relative permittivity or specific inductive capacity or dielectric coefficient can also be defined as the ratio of the electrostatic force between two charges separated by a certai distance in vacuum to the electrostatic force between the same two charges separated by the same distance in that medium.
Dielectric constant has no unit
