WebApr 1, 2024 · Permittivity. Permittivity ( ϵ, F/m) describes the effect of material in determining the electric field intensity in response to charge. In free space (that is, a perfect vacuum), we find that ϵ = ϵ 0 where: ϵ 0 ≅ 8.854 × 10 − 12 F/m. The permittivity of air is only slightly greater, and usually can be assumed to be equal to that of ...
