Nonlinear capacitor consist of 14 metal plates isolated by nonlinear dielectric material.
Relative permittivity of dielectric material - nonlinear.
Voltage V0 = 0.. 240 V.
Calculate C(V) curve.
To calculate C(V) curve we should make a set of experiments: change the voltage and measure the charge q. The capacitance is C = q / V.
To automate the task lets apply the time-dependent voltage V(t) = Vmax*t, where t - is time. Thus we replace the series of problems with one time-dependent problem. After the problem is solved QuickField can calculate q(t) automatically.
