In Memory of Jack

This book will help you learn the fundamentals of electricity and electronics without taking a formal course. It can serve as a do-it-yourself study guide or as a classroom text. This sixth edition contains new material about switching power supplies, class-D amplifiers, lithium-polymer batteries, microcontrollers, and Arduino.

Youll find a multiple-choice quiz at the end of every chapter. The quizzes are open-book, meaning that you may (and should) refer to the chapter text as you work out the answers. When you have finished a chapter, take the quiz, write down your answers, and then give your list of answers to a friend. Have the friend tell you your score, but not which questions you got wrong. That way, you can take the test again without bias.

When you reach the end of each section, youll encounter a multiple-choice test. A final exam concludes this course. The questions are a bit easier than the ones in the chapter-ending quizzes, but the tests are closed-book. Dont refer back to the text as you take the part-ending tests or the final exam. For all 35 chapter-ending quizzes, all four tests, and the final exam, a satisfactory score is at least three-quarters of the answers correct. The answer key is in .

If you need a mathematics or physics refresher, you can select from several of Stan Gibiliscos McGraw-Hill books dedicated to those topics. If you want to bolster your mathematics knowledge base before you start this course, study Algebra Know-It-All and Pre-Calculus Know-It-All. On the practical side, check out Electricity Experiments You Can Do at Home.

If you get bitten by the microcontroller bug, then youll find Simon Monks Programming Arduino: Getting Started with Sketches and Programming Arduino Next Steps: Going Further with Sketches useful companions to this book.

The authors welcome ideas and suggestions for future editions.

YOU MUST UNDERSTAND SOME PHYSICS PRINCIPLES TO GRASP THE FUNDAMENTALS OF ELECTRICITY and electronics. In science, we can talk about qualitative things or quantitative things, that is, what versus how much. For now, lets focus on what and worry about how much later!

All matter consists of countless tiny particles in constant motion. These particles have density far greater than anything we ever see. The matter we encounter in our everyday lives contains mostly space, and almost no real stuff. Matter seems continuous to us only because of the particles submicroscopic size and incredible speed. Each chemical
