A majority of the texts available for teaching electronic troubleshooting are based heavily on theory and complex formulas that are not required or desired in a hands-on teaching approach. In contrast, this book enables technicians to understand electronic repair problems without introducing high-level engineering formulas. This objective is achieved by presenting applications-oriented problem-solving techniques along with pictorial representations that replace complicated theory-oriented and equation-intensive learning processes. Includes chapters on industrial safety systems, AC/DC theory, reading electronic schematics, semiconductor devices, power supplies, and much more. Lab assignments, worksheets, and review questions are at the end of each chapter. Appendices include information about resistor color codes, common electronic symbols, technical math, and useful Web sites.
