About Of the Book:
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 textbook. 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. One of the special features of this book is the presentation of PSpice, which is a computer circuit analysis or simulation program that is suitable for use on personal computers (PCs). PSpice is similar to SPICE, which has become the standard for analog circuit simulation for the entire electronics industry. Another special feature is the presentation of operational amplifier (op-amp) circuits. Both of these topics are new to this second edition. Another topic that has been added is the use of advanced scientific calculators to solve the simultaneous equations that arise in circuit analyses. Although this use requires placing the equations in matrix form, absolutely no knowledge of matrix algebra is required. Finally, there are many more problems involving circuits that contain dependent sources than there were in the first edition. I wish to thank Dr. R. L. Sullivan, who, while I was writing this second edition, was Chairman of the Department of Electrical Engineering at the University of Florida. He nurtured an environment that made it conducive to the writing of books. Thanks, are also due to my wife, Lois Anne, and my son Mathew for their constant support and encouragement without which I could not have written this second edition.
I have always tried to impress upon my students that a course on electric circuits involves much more than learning set procedures and techniques or writing down equations and solving for the variables involved. The factual knowledge acquired in these courses is much less important than the insight gained into concepts and their interrelations, and the problem-solving approach that is learned. Factual knowledge is liable to be forgotten or become obsolete, whereas a grasp of fundamentals and the pursuit of creative problem-solving become integral to the mindset of true engineering professional. This book reflects such a philosophy. No special preparation is assumed on the part of the student beyond trigonometry, elementary calculus, and some basic physics. The discussion starts from almost level zero in circuit theory. Mathematics alone is not relied upon to present concepts and relations. Qualitative and physical explanations and interpretations are emphasized whenever possible.
