Permittivity of free space翻译
WebThe permittivity of an insulating, or dielectric, material is commonly symbolized by the Greek letter epsilon, ε; the permittivity of a vacuum, or free space, is symbolized ε 0; and their … 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) … Zobraziť viac 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 … Zobraziť viac 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.
