Relative Permittivity is the ratio of the Permittivity of a medium compared to the Permittivity of Free Space.

Relative permittivity of a medium is denoted with the Greek letter epsilon followed by a subscript of r (\(\varepsilon_r\)).

Relative permittivity has no units.

When an electrostatic field propagates through a medium which is not the vacuum the permittivity of that medium is given by the product of its relative permittivity and the permittivity of free space.
