Summary of the subject: Electrical engineering is a broad field of practical application of electromagnetic phenomena. Electrical engineering is a discipline that deals with the calculation and study of phenomena characterized by the concepts of electric currents, voltages, powers, magnetic fluxes, as well as the concepts of electric intensity and induction of magnetic fields. Studying the course "Fundamentals of electrical engineering" requires knowledge of physics courses, namely the section "Electricity and magnetism", and especially mathematics, primarily sections: systems of linear algebraic equations, matrix theory, derivative and integral, differential equations, functional series, integral Laplace transforms, vector algebra. The theoretical provisions of the course are thoroughly learned only when they are used to solve specific problems. Such tasks are faced not only by specialists in electrical engineering specialization, but also by engineers in other areas, because no branch of modern industry can do without the use of electrical equipment.
