This book presents the analysis of simple electrical circuits in steady-state sinusoidal operating conditions. It creates a foundational background of knowledge for a more effective understanding of the topics addressed in Power Systems Analysis and includes the essential knowledge required for an Electrical Engineer.

The material of the book is presented in such a way as to teach the understanding of how new knowledge combines with previous knowledge in solving practical problems, which is an essential and fundamental knowledge that should be provided in the early years of study and will characterize the emerging Electrical Engineer. It also aims to develop students' abilities to solve practical problems through understanding of concepts rather than through mechanistic techniques.

Understanding this problem-solving process is a prerequisite for addressing the future challenges that students will encounter in their studies. A key tool in achieving these aforementioned goals is the many examples that accompany the text. An essential complement to understanding the topics related to Circuit Power Analysis is the problems and their solutions found in the appropriate chapters.

For the best possible outcome, the reader of the book should refer to the solutions of the problems only to confirm the correctness of their own solution or if their own attempts at solving them were unsuccessful. The problems that are solved have been selected to clarify the important issues that arise when solving power circuits. Their goal is to convey to the engineer the methodology of thinking for solving problems using both traditional and modern methods.
