WebThe permittivity of free space is a physical constant that reflects the ability of electrical fields to pass through a classical vacuum. The constant is equal to approximately 8.854 x 10 -12 F/m ( farad per meter), with a relative standard uncertainty of 1.5 x 10 -10. WebSep 12, 2024 · where ϵ is the permittivity (SI base units of F/m). In simple media, ϵ is a real positive value which does not depend on the time variation of E. That is, the response ( D) to a change in E is observed instantaneously and without delay.
