Analysis and comparison of the analitical and experimental methods modeling the electrostatic field

Electrostatic field is a particular case of the electromagnetic field. The problems, solved in electrostatics, are concerned with determining the laws of variation of the electric field intensity E and electric potential V in all analyzed points in the field considered. Thus, it assumes that the potentials and the geometry dimensions of the objects, generating the field, are known. In this paper a detailed analysis and comparison of the existing methods, describing the behavior of a considered electrostatic field, is made. Two models, based on the pan filled with electrolyte and on the electrical-conductivity paper, respectively, are proposed and realized experimentally. They are applied for determining the capacity of the wires line in laboratory environment. The complete analysis and comparison of the results from both methods, is made.
