Permittivity - an overview ScienceDirect Topics

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) physical constant. Its CODATA value is: ε0 = 8.8541878128(13)×10 F⋅m (farads per meter), with a relative uncertainty of 1.5×10 . Webb1 apr. 2024 · 10.1: Permittivity of Some Common Materials.
