Technical Electrodynamics| Резюме: | The electric model is investigated as a simplified threeelementary chart of substitution of interfacial area of metallic electrode – conductive liquid (interface). The results of experimental researches of constituents of impedance are presented in the range of frequencies higher 10 kHz for two types of conductometry interface of Pt/Н2О and Pt/KCl. The change of two-element chart of substituting for a cell with successive on a parallel chart depending on working frequency and permittivity of solution is proved. Dependence of pure resistance of cell with solution from frequency is investigated. In theory it is set and experimentally proved that the slump of frequency dependence is conditioned by the presence of currents of displacement in low-mineralized solutions. For the calculation of frequency of slump it is possible to use not only the parameters of volumetric impedance (resistance and capacity) but also parameters of environment (electrolytic conductivity and inductivity).
