Permittivity: Its unit and dimensional formula

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 As indicated above, the parameter ε0 is a measurement-system constant.
