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 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 … See more • Casimir effect • Coulomb's law • Electromagnetic wave equation • ISO 31-5 See more Historically, the parameter ε0 has been known by many different names.
