We consider an electrostatic field created by a system of two like or unlike charges. Calculations are performed for charges located on spherical non-conducting surfaces, and the results obtained can be generalized to any shape of charged objects. The purpose of the study is to improve the correctness of electrostatic calculations, eliminating the possibility of obtaining unreliable results in the form of infinitely large energy. Electrostatic methods are used. The field energy is determined in two ways – through energy density and integration over the volume occupied by the field, as well as by calculating the work done during the hypothetical movement of charged objects. Three definitions of different types of electrostatic energy are given. Formulas are obtained for the corresponding energies for various combinations of charges.
total, conditional realizable, unrealizable, stored energy; like, unlike charges.
