The book "Calculation of linear electrical circuits: educational manual on the discipline "Electrical engineering with the basics of energy saving" by C. In. Batiukova is an indispensable source of knowledge for students, graduate students and specialists seeking to deepen their knowledge in the field of electrical engineering and energy conservation. This two-part manual offers readers not only the theoretical foundations but also the practical skills needed to successfully calculate and analyze linear electrical circuits. From the first pages of the book, the author immerses the reader in the fascinating world of electrical engineering, where each formula and each equation become the key to understanding the complex processes occurring in electrical systems. Batyukov masterfully explains the basic principles of electrical circuits, ranging from the simplest elements, such as resistors and capacitors, to more complex systems, including transformers and generators. The reader will be able not only to master the basic concepts, but also to learn how to apply them in practice, which makes the manual especially valuable for future engineers and technicians. The book will be of interest not only to students of technical specialties, but also to those who work in the field of energy, electrical engineering and related disciplines. She will be an excellent assistant for teachers who want to supplement their lectures with relevant examples and tasks. The manual will also be useful to those who are interested in modern energy saving methods and want to learn how to optimize electrical circuits to increase their efficiency. One of the key themes raised in the book is the importance of energy conservation in today's world. Batyukov focuses on how the correct calculation and design of electrical circuits can significantly reduce energy consumption and, therefore, reduce electricity costs. This is especially true in the face of rising energy prices and the need to transition to more sustainable energy sources. Readers will be able to see how theoretical knowledge is used to solve real problems, which makes studying the material not only useful, but also fascinating. The author's style is distinguished by clarity and accessibility, which allows even beginners in the field of electrical engineering to easily assimilate complex concepts. Batyukov uses many illustrations, diagrams and examples from practice, which makes the material clear and understandable. His previous works, such as Fundamentals of Electrical Engineering and Energy Saving in Electrical Systems, have also received positive reviews for their accessibility and practical focus. If you are looking for a tutorial that will help you not only to master the theory, but also to learn how to apply knowledge in practice, “Calculation of linear electrical circuits” will be an excellent choice. This book will not only expand your horizons in the field of electrical engineering, but will also prepare you for solving urgent problems related to energy saving.
