Description

For non-electrical engineering majors taking the introduction to electrical engineering course.

Electrical Engineering: Concepts and Applications is the result of a multi-disciplinary effort at Michigan Technological University to create a new curriculum that is attractive, motivational, and relevant to students by creating many application-based problems; and provide the optimal level of both range and depth of coverage of EE topics in a curriculum package.

Features

• Curriculum for non-EE majors: A multi-disciplinary effort at Michigan Technological University, with support from the U.S. National Science Foundation’s Engineering Education division, aimed to create a curriculum that (1) encourages students to pursue the life-long learning necessary to keep pace with the rapidly-evolving engineering industry and emerging interdisciplinary technologies, (2) maintains sufficient connection between the students’ chosen engineering fields and class content; and (3) motivates and excites the students about the importance of EE concepts to their discipline and career. The group’s curriculum reform efforts were informed by a nationwide survey of engineering schools. The survey outcomes were analyzed to fine tune different curriculum options for this course for different engineering disciplines, and then used as a layout to create a new textbook. This book’s diverse topics address the mixed survey response and allow it to address the needs of lecturers in different institutions worldwide.
• Application-based examples: A large number of application-based examples selected from different engineering fields are included in each chapter. They aim to bridge EE and diverse non-EE areas. These examples help address the question: “why should I take this course?” Non-EE students will better understand: (1) why they should learn how to solve circuits; and; (2) the applications of solving circuits in mechanical, chemical, and civil engineering areas.
• PSpice lectures, examples, and problems: The text offers a distributed approach for learning PSpice. Chapter 2 provides an initial PSpice tutorial, and new skills are added in Chapters 3 - 11. This part includes lectures that teach students how to use PSpice and can be considered as an embedded PC-based lab for the course. PSpice-specific examples and end-of-chapter PSpice problems help students better understand the process of building a circuit and getting the desired results.
• Innovative chapters: Based on a nationwide survey, the topics in these chapters have been highlighted by many professionals as important for this course. Each instructor has the liberty to include or exclude some of these topics from his/her curriculum. Some topics include:
  • Chapter 1-Case Study uses real life mechanical, chemical, and civil engineering scenarios to present the applications of electrical engineering and better motivate students in their chosen fields of study. These case studies are reintroduced as topics are covered later in the book.
  • Chapter 7-Frequency Response with MATLAB and PSpice discusses the frequency response of circuits, introduces different types of filters and uses MATLAB and PSpice examples and end-of chapter problems. This chapter creates an opportunity for students to learn some features of MATLAB software through an integrated study using both PSpice and MATLAB.
  • Power Coverage-Chapters 9, 12, 13: Based on the nationwide survey, and motivated by concerns about global warming and the need for clean energy, industry respondents requested a more thorough treatment of power.
    • Chapter 9 introduces the concept of three phase systems, transmission lines, their equivalent circuits, and power transfer.
    • Chapter 12 studies another important topic of energy transfer - transformers.
    • Chapter 13 studies the topic of motors and generators and introduces many applications of both.
  • Chapter 15-Electrical Safety discusses interesting electric safety topics useful in the daily life of consumers or engineers working in the field.
• Examples and sorted end-of-chapter problems: The book features more than 1100 examples and end-of-chapter problems (solutions included). End-of-chapter problems are sorted to help instructors select basic, average, and difficult proble
