Electrical Principles and Practices is an introduction to electrical and electronic principles and practices and their uses in residential, commercial, and industrial applications. This new edition has been reorganized to provide coverage of key electrical concepts at the beginning of the text. Other chapters have been expanded to include greater coverage on personal protective equipment, NFPA 70E, basic first aid, test instruments, printreading, and programmable logic relays.

Includes a CD-ROM in the back of the book is designed as a self-study aid to enhance text content. The CD-ROM includes Quick Quizzes®, an Illustrated Glossary, Math Formulas, and Reference Material. The Quick Quizzes® provide an interactive review of the topics covered in the chapters. The Illustrated Glossary provides a helpful reference to key terms included in the text. Selected terms are linked to illustrations, video clips, and animated graphics that augment the definition provided.

The Math Formulas provide formulas for interactive calculation and application of Ohm’s Law, the Power Formula, series circuits, parallel circuits, electric motor operation, and RCL circuits. The Reference Material button accesses links to Internet sites that contain related electrical-product manufacturer and reference information..
