Relative permeability of the medium
The resistance of the capacitor with plane-parallel plates of area S, parallel placed at the distance x to each other, with dielectric of constant permitivity ε and resistivity ϝ, that is charged with charge q and -q, is:
R = (ϝ*x)/A [Ω]
R = (ϝ*d)/A [Ω]
R = (ϝ*d)/S [Ω]
R = (ϝ*x)/S [Ω]
The resonance is obtained by the variation of the following parameters:

When applying the cyclic (loop) currents method:
The currents on the circuit branches have their values equal with the chosen fictive currents
The directions of the fictive currents are chosen based on some rules
The specific method equations system has b=I-n+s equations
The self-impedance values have all the negative sign when explicitly written
