Permittivity of vacuum unit
WebThe vacuum permittivity measures the ability of a vacuum to support an electric field. A vacuum a dielectric like any other substance in that it only supports electric fields to some extent. The permittivity is a measure of opposition - the higher the permittivity, the lower the electric field from a given source of electric field (a charge). WebThe vacuum permittivity, also called the absolute permittivity, is the measure of how an electric field affects and is affected by a dielectric material in vacuum. The permittivity of vacuum is a physical constant that is represented by the Greek letter ε (epsilon). The value of ε in SI units is 8.854 187 817 × 10−12 farads per meter (F/m).
