Combine comprehensive coverage of basic electrical theory with practical "how to" information to prepare students for real practice with DELMAR''S STANDARD TEXTBOOK OF ELECTRICITY, 7E by Stephen Herman. This edition covers all aspects of basic theory with no assumption of prior electrical knowledge. The author also limits math to basic algebra and trigonometry with step-by-step examples. Quality schematics and illustrations guide students through basic electrical circuits; DC and AC theory; and equipment such as meters, transformers and motors. Numerous examples demonstrate how to complete common tasks electricians perform, while succinct units cover only one or two topics each to ensure clarity. In addition, new coverage of spike and surge protection and motor installation complies with the 2017 NEC. MindTap online resources are also available with interactive multimedia and options to customize and track and report progress.
