Electric Circuits, 9/e (IE-Paperback)
暫譯: 電路學，第9版 (IE-平裝本)

Description
Electric Circuits 9/e is the most widely used introductory circuits textbook of the past 25 years. As this book has evolved over the years to meet the changing learning styles of students, importantly, the underlying teaching approaches and philosophies remain unchanged. The goals are:

To build an understanding of concepts and ideas explicitly in terms of previous learning

To emphasize the relationship between conceptual understanding and problem solving approaches

To provide students with a strong foundation of engineering practices.

New to This Edition
The ninth edition revision of Electric Circuits began with a thorough review of the text by instructors who currently use Electric Circuits and those who use other texts. This review provided a clear picture of what matters most to instructors and their students and led to the following changes:

Problem solving is fundamental to the study of circuit analysis. Having a wealth of new problems to assign and work is a key to success in any circuits course. Therefore, existing end-of-chapter problems were revised, and new end-of-chapter problems were added. The result is a text with approximately 75% new or revised problems compared to the previous edition.

Both students and instructors want to know how the generalized techniques presented in a first-year circuit analysis course relate to problems faced by practicing engineers. The Practical Perspective problems provide this connection between circuit analysis and the real world. We have expanded the use of the Practical Perspectives so that they now appear at the start of every chapter. This problem is solved, at least in part, at the end of the chapter, and additional end-of-chapter problems can be assigned to allow students to explore the Practical Perspective topic further.

Examples embedded in the text that illustrate the application of concepts just presented are an important tool to improve student understanding. The ninth edition adds new examples and now all chapters except Chapter 12 have a minimum of four examples. Chapter 12, which presents an introduction to Laplace transform techniques, is comprised of a collection of examples, but does not follow the format of concept-example employed by the other chapters.

Previous editions of Electric Circuits contained many end-of-chapter problems with circuits constructed from components with standard values. These circuits could actually be constructed and tested in a laboratory. New to the ninth edition is Appendix H, which lists standard values for resistors, inductors, and capacitors. Also new are end-of-chapter problems for most chapters that ask students to use components from Appendix H to construct circuits that meet particular requirements. The use of standard components is another effort to tie circuit analysis concepts to real-world circuits.

Previous editions of Electric Circuits have been published with an optional separate paperback manual presenting an introduction to PSpice and its use in simulating circuits a student encounters in their study of linear circuits With the ninth edition, students and instructors can choose from two circuit-simulation manuals-PSpice, or MultiSim. Each manual presents the simulation material in the same order as the material is presented in the text. These manuals continue to include examples of circuits to be simulated that are drawn directly from the text. The text continues to indicate end-of-chapter problems that are good candidates for simulation using either PSpice or MultiSim.

Students who could benefit from additional examples and practice problems can use the Student Workbook. This workbook has examples and problems covering the following material: balancing power, simple resistive circuits, node voltage method, mesh current method, Thévenin and Norton equivalents, op amp circuits, first-order circuits, second-order circuits, AC steady-state analysis, and Laplace transform circuit analysis.

Instructors and students benefit greatly from thoughtful methods of assessing student learning. The ninth edition makes PowerPoint presentations available to instructors that include embedded assessment questions. During a lecture, the instructor can present material using PowerPoint, pose a question to the students concerning that material, and allow students to respond to the question. Results from student responses are immediately available to the instructor, providing real time information about the students' comprehension of the material. This immediate feedback allows the instructor go back and revisit material the students did not comprehend, or to continue presenting new material if comprehension is satisfactory.

Every new copy of the book now comes with access to Video Solutions and a Pearson eText. Video solutions are complete, step-by-step solution walkthroughs of representative homework problems. The Pearson etext is a complete on-line version of the book that includes highlighting, note-taking and search capabilities.
