Capacitance of coaxial cable
Nov 14, 2020 · 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. Capacitance’and’Inductance’’ per’UnitLength’! = permativity of material µ= permeability of material h d D Typically’derived’in’your’Coaxial cables transmit signals through the center wire. To ensure a quality signal travels the length of the cable a metal shield is needed. Both components receive a current simultaneously, generating a magnetic field. This allows the signal to remain intact and not bleed out like it would without the shield.
