Absolute permittivity via relative permittivity

Absolute permittivity of a medium can be expressed as the product of its relative permittivity and vacuum permittivity.

Notes:

1. This equation can be seen as the definition of relative permittivity.

Notation:

1. \(\varepsilon_0\) (epsilon_0) is vacuum_permittivity.
