Summary

This exciting full-color book is the most comprehensive text book on DC/AC circuits and machines for electrical students on the market today. It provides complete coverage of concepts relating to electrical theory, as well as giving practical "how-to" examples of many of the common tasks that electricians must perform. The book has been organized so that all relevant information is located within a given chapter, making it easy to access and easy to teach topics in any order. With its visually appealing, easy-to-understand coverage of alternating current theory, and expanded coverage of topics such as transformers and electrical filters, Delmar's Standard Textbook of Electricity, 2E continues to set the standard in DC/AC circuits and machines.ALSO AVAILABLELab Volt Lab Manual, ISBN: 0-8273-8552-8Standard Lab Manual, ISBN: 0-8273-8554-4INSTRUCTOR SUPPLEMENTS CALL CUSTOMER SUPPORT TO ORDERInstructor's Guide, ISBN: 0-8273-8551-XLab Volt Solutions Manual, ISBN: 0-8273-8553-6Transparency Masters, ISBN: 0-8273-8556-0
