Book Description

Electricity offers a complete introduction to the nature of electricity for those who want to know more about electricity but do not find the time to struggle through complicated handbooks. It explains what electricity and magnetism are, how batteries work, the difference between DC- and AC-fields, what conductors, inductance and capacitance are, and many other things. The text provides examples of practical electrical applications and includes checkpoints, self-tests, and a final examination with questions based on actual operator certification exams. Each chapter is illustrated by comprehensive figures, and particularly important key points are stressed where necessary.

Reviews

"It is written for those who want to know more about electricity but do not find the time or the courage to struggle through complicated handbooks. It is made for those who routinely use very sophisticated electrical devices without really knowing what they are doing. And knowing what you are doing, how things work, certainly contributes to better performances at work and to one's wellbeing... This book explains in simple words what electricity and magnetism are, how batteries work, what's the difference between DC- and AC-fields, what conductors, inductance and capacitance are, and many other things. It also gives examples of practical electrical applications and provides at the end of each chapter the opportunity to test one's acquired knowledge by a number of self-tests. Each chapter is illustrated by comprehensive figures, and particularly important key points are stressed where necessary without overwhelming the reader with too much data and overloaded pages... I really appreciated this book and I am pretty sure that many students and professionals will find a lot of benefit in reading it."
