The concept of electric charge, the calculation of DC electrical circuits

Calculation of electrical circuits according to Kirchhoff's law. Kirchhoff's laws are used in the calculation of complex (branched) electrical circuits. Kirchhoff's laws are one of the basic laws of the theory of electrical circuits. in this article, Kirchhoff's 1st law, the 2nd law, the method of circuit currents, nodal potentials are fully considered. The scheme that is most applicable in practice is chosen.
