WebVacuum 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. WebAug 30, 2010 · Dielectric constant (Dk or relative permittivity) is a parameter that design engineers use constantly, often without fully understanding it.
