Electricity: Principles and Applications, 8/e (Hardcover)
暫譯: 電力：原理與應用，第8版（精裝本）

This widely-used text prepares students for entry-level jobs in electronics, electrical trades and related fields. Its level and approach are ideal for both electronics and electricity programs looking for a relatively short, applied book covering DC/AC circuits. Additional chapters on topics such as safety, transformers, motors, instrumentation, and residential wiring are also included. No prior knowledge of electricity is assumed; the only prerequisites are arithmetic and basic algebra. Practical skills are emphasized throughout the text, and supported in the hands-on work provided in the companion Experiments Manual. MultiSim circuit files are provided, on a bound-in CD ROM, for those who want to bring software simulation work into their classes and labs.

• • Practical, easy-to-understand explanation of DC and AC circuits; students with all math backgrounds will find the book readable and accessible.
  • Frequent Self-Test questions and worked examples provide students with immediate feedback and step-by-step procedures for learning key concepts and applications.
  • Students can now learn about new energy sources in Appendix K, Renewable Energy Sources and Technologies
  • Contains classroom PowerPoint^R presentations for every chapter, EZ-Test Generator, supplemental PowerPointR presentations, and more. PowerPointR presentations have been revised and updated, with video clips added in several places.
  • Experiments Manual for Electricity: Principles and Applications correlates with the text and helps students gain practical, hands-on experience and troubleshooting skills. MultiSim files are available for those who integrate simulation with their lab experiments.
  • Popular features such as learning outcomes, highlighted key terms, color-coded circuit components, and About Electronics have been retained and updated.
  • Concepts build from section-to-section and chapter-to-chapter, with tests at regular intervals and review questions at the end of each chapter.
  • New To This Edition
    • Re-emphasized the color and proper use of the neutral conductor.
    • Added an EXAMPLE illustrating the current flow in each conductor when a short develops.
    • Expanded the discussion on AFCI protection.
      New Multisim-11 files have been created. The files are located on the CD-ROMs for the textbook and the Experiments Manual, as well as on the Online Learning Center


• Electricity: Principles and Applications has been revised to include more Examples, MultiSim Files for version 11.0, clearer explanations, and more Self-Tests and review questions for your students. The following is a chapter-by-chapter list of major changes to the textbook:
  
  Chapter 1
  • Expanded the section on “efficiency” to include information on neon light bulbs and LEDs.
  • Added a new EXAMPLE that examines the efficiency of a complete system (i.e. a battery and light bulb circuit). The new Self-Test question 11, and the answer to question 11 at the end of the chapter, follow up on working with system efficiency.
  • Added new Self-Test and “Chapter Review” questions and problems.
  Chapter 2
  • Changed the concluding paragraph of the “current in a vacuum” section to emphasize that devices that relied on thermionic emission and current in a vacuum have mostly been replaced by LCDs and solid-state devices.
  • Added discussion of when to italicize a symbol (abbreviation) used in formulae.
  • Added more EXAMPLES that show how to use "powers of 10". EXAMPLE 2-9 shows how to express a base 10 number of less than one in the power-of-ten format. EXAMPLE 2-10 shows how to add, subtract, and divide numbers expressed in powers-of-ten. Also added Self-Test question 59 and its answer to give more practice on the procedures shown in the two added examples.
