# The dielectric Constant of a metal is

The dielectric constant of metals is infinite.

The dielectric constant of metal is infinite as the net electric field inside the metal is zero.

The dielectric constant is defined as the ratio of the permittivity of a substance to the permittivity of free space. As the electric flux density increases, the dielectric constant increases.

The dielectric constant is sometimes also known as specific inductive capacity or relative permittivity.
