En -Teach your self electricity and electronics

Preface

This book is for people who want to learn basic electricity, electronics, and communications

concepts without taking a formal course. It can also serve as a classroom

text. This third edition contains new material covering acoustics, audio,

high-fidelity, robotics, and artificial intelligence.

I recommend you start at the beginning of this book and go straight through.

There are hundreds of quiz and test questions to fortify your knowledge and help

you check your progress as you work your way along.

There is a short multiple-choice quiz at the end of every chapter. You may (and

should) refer to the chapter texts when taking these quizzes. When you think you’re

ready, 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.

The answers are listed in the back of the book. Stick with a chapter until you get

most of the answers correct. Because you’re allowed to look at the text during

quizzes, the questions are written so that you really have to think before you write

down an answer. Some are rather difficult, but there are no trick questions.

This book is divided into four major sections: Direct Current, Alternating Current,

Basic Electronics, and Advanced Electronics and Related Technology. At the

end of each section is a multiple-choice test. Take these tests when you’re done with

the respective sections and have taken all the chapter quizzes. Don’t look back at the

text when taking these tests. A satisfactory score is 37 answers correct. Again, answers

are in the back of the book.

There is a final exam at the end of the book. The questions are practical, mostly

nonmathematical, and somewhat easier than those in the quizzes. The final exam

contains questions drawn from all the chapters. Take this exam when you have finished

all four sections, all four section tests, and all of the chapter quizzes. A satisfactory

score is at least 75 percent correct answers.
