Master the fundamentals of alternating currents with a trusted classic in electrical engineering.
This volume, part of The Elements of Electrical Engineering series, covers theory and practical design for technical schools and colleges. In the second edition, it presents the core concepts of alternating electromotive force, measurement, and the machines that use AC power, including transformers, motors, and transmission lines.
The book outlines the operating principles of the alternator, explaining how rotating magnetic fields generate alternating current and how different designs—revolving-armature, revolving-field, and inductor types—are used in industry. It also introduces measurements, complex quantities, polyphase systems, and methods for analyzing currents, voltages, and power in AC circuits. Readers will find clear explanations of transformer construction, losses, regulation, and the all-important concept of efficiency, as well as practical guidance for calculating performance and rating transformers.
What you’ll experience
- A structured tour of alternating-current theory, from electromotive force to practical machine design
- In-depth treatment of the transformer: losses, regulation, efficiency, and loading
- Explanation of induction motors and synchronous motors, including performance considerations
- The circle diagram approach for visualizing motor and transformer behavior
