Page 19 - Teach Yourself Electricity and Electronics

Preface

This book is for people who want to learn basic electricity, electronics, and com-
munications concepts without taking a formal course. It can also serve as a class-
room 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 Cur-
rent, 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, an-
swers 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 fin-
ished all four sections, all four section tests, and all of the chapter quizzes. A satis-
factory score is at least 75 percent correct answers.
With the section tests and final exam, as with the quizzes, have a friend tell you
your score without letting you know which questions you missed. That way, you will
not subconsciously memorize the answers. You might want to take a test two or
