Издание на английском языке
The book is devoted to the basics of electrical engineering and electronics, intended for undergraduate students. It covers key topics, starting with Ohm's and Kirchhoff's laws, and further examines single-phase and three-phase circuits, electrical wiring, as well as the use of electrical machines and transformers in everyday life. The book also discusses circuit analysis methods, network theorems, transients, and resonant phenomena in AC circuits. Each topic is accompanied by illustrations and examples, which helps readers better understand the theory and apply it in practice. The author expresses his gratitude to the reviewers and colleagues for their support and valuable advice.
