WebApr 6, 2024 · As long as I know, there is no practical way to measure permittivity of conductor in low frequency. So I often assume that ϵ = ϵ 0. The permittivity is insulator specific quantity, I believe it is hard to apply permittivity concept to conductors in low frequencies.

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 ...
