The book contains basic information on electrical engineering, direct current, chemical effects of direct current, thermal effects of electric current, electromagnetism and electromagnetic induction, single-phase and three-phase alternating current, transformers, asynchronous and synchronous motors, DC machines, electrical measuring instruments and methods measurements, batteries, wiring, rules for drawing up and reading diagrams. The book pays great attention to the production of electrical work.It also provides information on safety in electrical installations.The book can be used as a teaching aid for students of vocational schools in which electrical engineering is an independent and special subject. In addition, this book can be a textbook for secondary school students with industrial training, as well as for advanced training and self-education of electrical workers. Knowledge of mathematics in the volume of 8 classes of secondary school enables students, when using the book, to freely operate with the mathematical material encountered in it.
