Vacuum permittivity , Online Physics, Physics Encyclopedia, ScienceThe physical constant ε0, commonly called the vacuum permittivity , permittivity of free space or electric constant, is an ideal, (baseline) physical constant, which is the value of the absolute dielectric permittivity of classical vacuum. Its value is [Math Processing Error] = 8.854 187 817... × 10 −12 F/m (farads per metre). It is the capability of the vacuum to permit electric field lines. This constant relates the ... Permittivity of Free Space Relative Permittivity Let's dicuss these types as below: Permittivity of Free Space (ε₀) The resistivity offered by the free space is the lowest and is the fundamental constant, it is referred as permittivity of free space and is denoted by ε₀. It has a value of 8.85 10-12 Farad/meter. Learn about Permittivity and Relative permittivity , what is the permittivity of vacuum, and what factors affect the permittivity of a material or substance.
