Vacuum permittivity - Wikipedia
Vacuum permittivity, commonly denoted ε0 (pronounced "epsilon nought" or "epsilon zero"), is the value of the absolute dielectric permittivity of classical vacuum. It may also be referred to as the permittivity of free space, the electric constant, or the distributed capacitance of the vacuum. It is an ideal (baseline) … See more
The value of ε0 is defined by the formula
$${\displaystyle \varepsilon _{0}={\frac {1}{\mu _{0}c^{2}}}}$$
where c is the defined value for the speed of light in classical vacuum in SI units, and μ0 is the parameter … See moreHistorically, the parameter ε0 has been known by many different names. The terms "vacuum permittivity" or its variants, such as "permittivity in/of vacuum", "permittivity of empty space", or "permittivity of free space" are widespread. … See more
1785Charles-Augustin de Coulomb publishes his law of electrostatic force between two point charges.Late 19th centuryThe rationalization of units is proposed to include a factor of 4π in Coulomb's law and other equations involving spherical geometry.1873Maxwell publishes A Treatise on Electricity and Magnetism, where he introduces the concept of displacement current and relates the electric constant to the speed of light and the magnetic constant.1881-1884The International Electrical Congress adopts the centimeter–gram–second electrostatic system of units (cgs esu system) as a standard for electrical measurements.1888Heinrich Hertz confirms the existence of electromagnetic waves by producing and detecting radio waves in his laboratory.1900-1905Max Planck and Albert Einstein develop the quantum theory of light, which explains the phenomena of black-body radiation and photoelectric effect that classical electromagnetism cannot account for.1946-1948The International Electrotechnical Commission (IEC) recommends the meter–kilogram–second–ampere (mksa) system as a practical system of units for electrical engineers. The ampere is chosen as the base unit of electric current, and the coulomb as the derived unit of electric charge.1960The General Conference on Weights and Measures (CGPM) adopts the International System of Units (SI) based on the mksa system, with seven base units including the ampere. The electric constant is given the name "vacuum permittivity" or "electric constant".2019The CGPM redefines the SI base units by fixing the numerical values of seven defining constants, including the elementary charge and the speed of light. The electric constant becomes a derived quantity that depends on the fine-structure constant. Its value is no longer exact, but has a relative uncertainty of 1.5×10−10.As indicated above, the parameter ε0 is a measurement-system constant. Its presence in the equations now used to define electromagnetic quantities is the result of the so-called … See more
By convention, the electric constant ε0 appears in the relationship that defines the electric displacement field D in terms of the electric field E and classical electrical polarization density P of the medium. In general, this relationship has the form: See more
