Power and Work Alternating Current AC. (English Edition)

Power and Work Alternating Current AC. (English Edition).

This book is written in a technical yet instructional style, aimed at students, professionals, and anyone interested in learning or updating their knowledge of alternating current. You will find a complete journey—from sinusoidal signals and RMS (effective) values to measurement; analysis of active, reactive, and apparent power; power-factor compensation; the behavior of R, L, and C loads and their combinations; and practical application in electrical systems. The goal is not only to help you understand the concepts, but also to develop skills to solve real-world problems with sound engineering judgment, in the context of 50 and 60 Hz networks and common references found in international standards.

Why is this book different?

- It integrates theory and practice: each chapter combines clear explanation, useful formulas, and self-assessment exercises with step-by-step answers.

- It uses modern resources: equivalent circuits, diagrams, and plots, along with the formulas most used in AC networks.

- It is geared toward engineering decisions: you will learn to estimate currents, select conductors, size transformers and capacitor banks, reduce (I^2R) losses, and evaluate power factor professionally.

- It supports your evaluation: it includes a series of solved problems–examples (1 through 7) and a final exam with 42 questions and detailed solutions, designed to confirm your progress and prepare you for your own applications.
