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.
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.
