As in earlier editions, the text takes readers from a straightforward discussion of basic electrical theory all the way to an in-depth treatment of alternating current, series and parallel circuits, as well as resistive, inductive and capacitative circuits. It highlights testing and troubleshooting procedures more than ever, and includes a number of new exercises. 450 illus.
