Preface

Electric fields play key roles in many practical problems and in various environmental phenomena. This book aims to help readers develop a better understanding of electrostatic fields using the form of problems and puzzles (presented as questions) and answers, instead of the tedious explanations often found in textbooks. In that sense, this book on electric fields is unique. The authors hope that with this approach, the book will attract the interest of students and engineers who study electric fields and of general readers who are interested in the subject. The book is filled with questions that have unexpected answers and with questions that are often misunderstood, or rarely completely understood. Most of these questions are original. At a glance, the questions look simple and very easy to answer; nevertheless, once readers try to solve them, they will find that the questions can be really tough nuts to crack. Lecturers could also use the questions in this book in their classes. This book will be useful not only from an academic or an educational point of view, but also for engineers working in such fields as electrical discharges and their applications, high-voltage equipment
