Building on the foundation established in Electricity 1, this book goes on to explore alternating current principles and concepts of inductive reactance, capacitive reactance, and impedance. Completely updated to the 2005 National Electrical Code?, Electricity 2 acquaints newcomers to the field with various types of alternating current circuits, while developing a solid understanding of the concepts of power, power factor, and power factor correction. Sample problems and solutions at the end of each unit provide a direct route to understanding as readers apply key electrical principles in realistic troubleshooting situations.
