The target audience colors everything about a book, being a major factor in decisions big and small, particularly both the pace and the overall writing style. Consequently, it is important to note that the authors have made the conscious decision to write this book to the student, and not to the instructor. Our underlying philosophy is that reading the book should be enjoyable, despite the level of technical detail that it must incorporate. When we look back to the very first edition of Engineering Circuit Analysis, it’s clear that it was developed specifically to be more of a conversation than a dry, dull discourse on a prescribed set of fundamental topics. To keep it conversational, the authors have had to work hard at updating the book so that it continues to speak to the increasingly diverse group of students using it all over the world.
Although in many engineering programs the introductory circuits course is preceded or accompanied by an introductory physics course in which electricity and magnetism are introduced (typically from a fields perspective), this is not required to use this book. After finishing the course, many students find themselves truly amazed that such a broad set of analytical tools have been derived from only three simple scientific laws—Ohm’s law and Kirchhoff’s voltage and current laws. The first six chapters assume only a familiarity with algebra and simultaneous equations; subsequent chapters assume a first course in calculus (derivatives and integrals) is being taken in tandem. Beyond that, the authors have tried to incorporate sufficient details to allow the book to be read on its own.
Engineering is an intensive subject to study, and students often find themselves faced with deadlines and serious workloads. This does not mean that textbooks have to be dry and pompous, however, or that coursework should never contain any element of fun. In fact, successfully solving a problem often is fun, and learning how to do that can be fun as well. Determining how to best accomplish this within the context of a textbook is an ongoing process. The authors have always relied on the often very candid feedback received from our own students at Purdue University; the California State University, Fullerton; Fort Lewis College in Durango; the joint engineering program at Florida A&M University and Florida State University; the University of Canterbury (New Zealand); the University at Buffalo, and Western Michigan University. The authors also rely on comments, corrections, and suggestions from instructors and students worldwide.
KEY FEATURES OF THE TENTH EDITION
Great care has been taken to retain key features from the ninth edition which were clearly working well. These include the general layout and sequence of chapters, the basic style of both the text and line drawings, the use of four-color printing where appropriate, numerous worked examples and related practice problems, and grouping of end-of-chapter exercises according to section. Transformers continue to merit their own chapter, and complex frequency is briefly introduced through a studentfriendly extension of the phasor technique, instead of indirectly by merely stating the Laplace transform integral. The authors also have retained the use of icons, an idea first introduced in the sixth edition.
Circuit analysis is a robust method for training engineering students to think analytically, step-by-step, and returning to check their answers. A flow chart illustrating a typical problem-solving methodology is presented in Chapter 1; these steps are explicitly included in one example in each of the subsequent chapters to reinforce the concept.
The introduction of engineering-oriented analysis and design software in the book has been done with the mind-set that it should assist, not replace, the learning process. Consequently, the computer icon denotes problems that are typically phrased such that the software is used to verify answers, and not simply provide them. Both MATLAB® and LTspice® are used in this context.
SPECIFIC CHANGES FOR THE TENTH EDITION INCLUDE：
⦁ New and revised end-of-chapter exercises
⦁ New figures and photos
⦁ Updated screen captures and text descriptions of computer-aided analysis software, and continued use of LTspice® as freeware software that is available natively on both Windows and Mac OS platforms
⦁ Updated worked examples and practice problems
⦁ Updates to the Practical Application feature, introduced to help students connect material in each chapter to broader concepts in engineering.
