Theoretical basis of the method of reproducing the unit of electrical capacitance

Conclusion

The most important feature of the theoretical capacitor is the constancy of the average value of the sum ¯C(¹). This means that the average value of the sum of the “crossed” capacitances, referred to unit length of the physical model, representing the capacitor of symmetrical construction (equality of the “crossed” capacitances), is a constant quantity (ɛ_oln 2/π). No less important is the fact that deviation from symmetry of the transverse cross section leads to correction terms of the second order of smallness. These conclusions can be used to estimate the effect on C(¹) of the parameters of the temperature field. However, the capacitance per unit length C(¹) is important and necessary but is still an insufficient parameter for estimating the total capacitance of the capacitor; i.e., for constructing its mathematical model, it is insufficient to multiply the above-mentioned constant by the total length of the physical model.
