The 23 chapters comprehensively cover the materials for a 1 semester college or 1 year high school class. The author provides enough conceptual, math and terminology depth to be accurate, while providing enough applications and clear illustrations to facilitate experiential learning. This text covers both electricity and electronics at an introductory level. The many projects would require help from an instructor or team to actually complete in a safe and timely manner. The author provides many relevant examples of usage, but the 1998 text is dated today. A good complement would be The New York Times Circuits: How Electronic Things Work. Students with only basic Algebra I and Geometry could complete this book, if motivated. Better to have completed Algebra II with a B level of mastery. This text could also be complemented with a Radio Shack electronics kit with 80 sample projects, which allows for more rapid application and less purchasing and experimentation. As the world employs more and more electricity and electronics, we have fewer and fewer individuals with even a basic understanding. Completing this text and some of the projects provides that basic grounding.
