Computing Coaxial Cable Capacitance through a DC and AC Power Supply

The aim of the present paper is to show the way of computing the Maxwell capacitance when applying a DC & AC voltage and comparing it with the analytic equation given in literature and show the advantages of this numerical method over analytical solution by changing the nature of the dielectric from air to PTFE. So, we will see the influence of the dielectric constant into calculating the capacitor and the impedance. In the case of applying an AC voltage, we vary the power supply frequency from 50 Hz to 1 kHz, 1 kHz - 1 MHz, 1 MHz - 5 MHz.
