Electric permittivity of copper

WebFeb 13, 2024 · Permittivity is the ability of a dielectric material to store electrical energy in an electric field. In the PCB industry, relative permittivity (ε r) and effective relative permittivity (ε reff) are synonymous with dielectric constant (D k) and effective dielectric constant (D keff) respectively.Herein, D k and D keff are substituted accordingly. By … WebNov 14, 2024 · Both of the cables are inside a bigger one: The black part is the isolation. Brown part is the copper itself. I also tried to calculate the capacitance with this below formula but I get a value of 1.5nF. The epsilon_r of the cable isolation is 2 so total electric permittivity is 2 * 8.8542*10^ (-12). I used 100m for l. a = r = 0.7mm.
