The Basics of Circuit Theory . for electrical engineering. and electricity. Special. universities]" is an indispensable textbook for students and specialists in the field of electrical engineering and electric power engineering, written by the author's team, which included G. In. Zeveke, P. A. Ionkin, A. In. Untouched and S. In. Fear. This edition offers a deep dive into the foundations of electrical circuit theory, making it ideal for both engineering students and practicing engineers seeking to update their knowledge. From the first pages of the book, the reader finds himself in the world of electrical circuits, where every element, whether resistor, capacitor or inductance, acquires its meaning and role. The authors masterfully explain complex concepts using accessible language and illustrative examples. They not only lay out the theoretical foundations, but also show how this knowledge is applied in practice. The reader will be able to understand how electrical circuits work, how to analyze and design them, which is a key skill for future engineers and technicians. The book will be interesting not only for students, but also for teachers who are looking for quality material for their courses. It is suitable for those who are fond of electrical engineering, electronics and related fields, as well as for those who want to deepen their knowledge in this important and in-demand field. The age category of readers varies from high school students studying physics and the basics of electrical engineering to undergraduate and postgraduate technical fields. The topics raised in the book cover a wide range of topics, from the basic concepts of the laws of Ohm and Kirchhoff to more complex topics such as the analysis of alternating current circuits and the use of complex numbers in calculations. The authors pay attention to both theoretical aspects and practical applications, which allows the reader not only to assimilate the material, but also to see its real application in life. This makes the book especially valuable for those who want not only to learn, but also to apply knowledge in real projects. The style of the authors is distinguished by clarity and logical presentation, which makes it easy to perceive even the most complex topics. They use many illustrations, diagrams and examples, which makes the learning process more exciting and effective.
