The Theoretical Foundations of Electrical Engineering, edited by C. G. Ivanova is an important work that covers a wide range of topics related to electrical engineering and its theoretical foundations. This textbook is created by a team of authors, which allows it to combine different approaches and views on the issues studied, making the material more multifaceted and accessible to perception. The book is intended for students of technical universities, graduate students and anyone interested in electrical engineering, physics and engineering disciplines. It will be useful both for those who are just beginning their journey in this area, and for those who already have certain knowledge and want to deepen their knowledge. Readers interested in topics such as electrical circuits, electromagnetic fields, theories, and methods of analysis will find much useful information in this book. From the first pages of "Theoretical Foundations of Electrical Engineering" immerse the reader in the world of electrical phenomena, starting with the basics and gradually moving to more complex concepts. The book covers such key topics as the laws of Ohm and Kirchhoff, the analysis of linear and nonlinear chains, and the foundations of electromagnetic theory. Each section is written with an emphasis on the practical application of theoretical knowledge, which makes the material not only theoretically sound, but also practically useful. One of the distinguishing features of this book is its structure. Each section begins with a brief introduction to the topic, followed by detailed explanations, examples, and tasks for self-decision. This allows the reader not only to absorb the material, but also to consolidate it in practice. In addition, the book uses illustrations and diagrams that greatly facilitate the understanding of complex concepts. The topics raised in the book are relevant and important in today's world. Electrical technologies permeate all areas of our lives, from consumer electronics to complex industrial systems. Understanding the basics of electrical engineering becomes essential for a successful career in engineering, energy, and many other fields. The book also addresses issues of sustainable development and energy efficiency, making it particularly relevant in the context of contemporary environmental challenges. The style of the authors is distinguished by clarity and accessibility, which makes complex technical aspects understandable to a wide audience. C. G. Ivanova and her colleagues successfully combine academic rigor with practical examples, which allows readers not only to study the theory, but also to apply the knowledge gained in practice. This makes the book an ideal guide for both students and professionals seeking to update their knowledge. If you are looking for literature on electrical engineering that combines theoretical depth and practical focus, “Theoretical Fundamentals of Electrical Engineering” is exactly what you need. The book will become an indispensable assistant in your training and professional activities, as well as open new horizons in understanding electrical processes and technologies.
