Electricity Demystified by Stan Gibilisco | PDF Free Download.
This book is for people who want to get acquainted with the concepts of elementary electricity and magnetism, without taking a formal course. It can serve as a supplemental text in a classroom, tutored, or home-schooling environment.
It can also be useful for career changers who want to become familiar with basic electricity and magnetism. This course is for beginners and is limited to elementary concepts. The treatment is mostly qualitative.
There’s some math, but it doesn’t go deep. If you want to study electronics following completion of this book, Electronics Demystified and Teach Yourself Electricity and Electronics, also published by McGraw-Hill, are recommended.
This book contains many practice quiz, test, and exam questions. They are all multiple-choice and are similar to the sort of questions used in standardized tests. There is an ‘‘open-book’’ quiz at the end of every chapter.
You may (and should) refer to the chapter texts when taking them. 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.
Stick with a chapter until you get most of the answers correct. This book is divided into sections called ‘‘Parts.’’ 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.
The section tests are ‘‘closed-book,’’ but the questions are not as difficult as those in the quizzes. A satisfactory score is 75%. There is a final exam at the end of this course. It contains questions from all the chapters.
Take this exam when you have finished all the sections and tests. A satisfactory score is at least 75%. With the section tests and the 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 each section test, and the final exam, two or three times. When you have got yourself a score that makes you happy, you can check to see where your knowledge is strong and where it is weak.
Answers to the quizzes, section tests, and the final exam are in an appendix at the end of the book. A table of circuit-diagram symbols is included in a second appendix. I recommend that you complete one chapter a week.
An hour or two every day ought to be enough time for this. When you’re done with the course, you can use this book as a permanent reference. Incidentally, don’t fly a kite in, or near, a thundershower to demonstrate that lightning is a form of electricity.
Ben Franklin did that experiment a long time ago (according to popular legend, at least) and escaped with his life. Some Russian scientists tried it (for real) and they got killed.
