Boyer. The book "DCAC Electrical Fundamentals" by John R. Boyer provides a comprehensive overview of the principles and concepts of direct current (DC) and alternating current (AC) circuits, as well as the practical applications of electrical engineering in various fields such as power generation, transmission, and distribution. The author emphasizes the importance of understanding the historical development of electrical technology and its impact on society, highlighting the need for a personal paradigm for perceiving the technological process of developing modern knowledge as the basis for the survival of humanity and the survival of the unification of people in a warring state. The book begins with an introduction to the fundamental concepts of electricity, including charge, voltage, current, and resistance, and progresses to cover more advanced topics such as circuit analysis, network theory, and electromagnetic waves. Throughout the book, Boyer emphasizes the importance of understanding the underlying principles of electrical engineering, rather than simply memorizing formulas and equations. He encourages readers to approach the subject with a critical and creative mindset, and to see the interconnectedness of electrical concepts with other areas of science and technology. One of the key themes of the book is the evolution of electrical technology and its impact on society. Boyer traces the development of electrical systems from the early experiments of scientists such as Benjamin Franklin and Alessandro Volta to the modern-day grid systems that power our homes, businesses, and transportation.
