Designed for vocational students who have completed a course in dc and ac circuits, this text is the second in the "Exploring" series and follows the same style and pedagogy as its predecessor, Exploring Electricity . It provides students with a smooth transition into semiconductor theory and circuits and brings them to the level of understanding a complete electronic system. The popular Skill-Builder feature walks the student through the math of circuit analysis with margin notes identifying formulas and referring to the basic electrical laws at each step.
