This new text makes learning the principles of electricity and electronics enjoyable and exciting for beginning automotive technician students. A relaxed writing style appeals to students, making it easy to learn the foundations of electricity, interpret the information in a wiring diagram, and diagnose problems quickly. Theory-based, repetitive exercises allow the student to master circuits and devices, while case studies expand students' ability to see the entire operation of an electrical system. A series of simple "hands-on" tests allows student to practice with live circuits. Theory and practical examples are interwoven throughout to give students a comprehensive understanding of automotive electricity and electronics.
