Summary

Mastering the theory and application of electrical concepts is necessary for a successful career in the electrical installation or industrial maintenance fields, and this newly revised, full color text delivers! Delmar's Standard Textbook of Electricity, 3E trains aspiring electricians by blending concepts relating to electrical theory with practical 'how to' information that prepares students for situations commonly encountered on the job. Topics span the major aspects of the electrical field including atomic structure and basic electricity, direct and alternating current, basic circuit theory, three-phase circuits, single phase, transformers, generators, and motors. This revision retains all the hallmarks of our market-leading second edition, but displays enhancements such as new up-to-date photos, bonus learning features to advance student retention, and a new e.resource for instructors that takes the guesswork out of classroom preparation.
