Preface
Studying from this book will help both electrical technology and electrical
engineering students learn circuit analysis with, it is hoped, less effort and more
understanding. Since this book begins with the analysis of dc resistive circuits
and continues to that of ac circuits, as do the popular circuit analysis textbooks,
a student can, from the start, use this book as a supplement to a circuit analysis
text book.
The reader does not need a knowledge of differential or integral calculus
even though this book has derivatives in the chapters on capacitors, inductors,
and transformers, as is required for the voltage-current relations. The few problems
with derivatives have clear physical explanations of them, and there is not a single
integral anywhere in the book. Despite its lack of higher mathematics, this book can
be very useful to an electrical engineering reader since most material in an electrical
engineering circuit analysis course requires only a knowledge of algebra. Where there
are different definitions in the electrical technology and engineering fields, as for
capacitive reactances, phasors, and reactive power, the reader is cautioned and the
various definitions are explained.
