Welcome to Prentice Hall's Companion Website for Floyd's Principles of Electric Circuits, 8th Edition, designed to help you in your quest to master the fundamentals of dc/ac circuits.

Study Guide
The study guide portion of this site contains practice quizzes that enable you to review concepts presented in your text. Questions are in multiple choice, true/false, and fill-in-the-blank format, and a "Hint" is provided for each question. The site is able to grade your work and will allow you to e-mail your results to your instructor.

Multisim^® Circuit Files
Circuit files are created in Multisim to correspond with specific figures in the text. These circuits were created for use with Multisim software, a schematic capture, simulation, and programmable logic tool produced by Electronics Workbench. These circuit files are available here in various Multisim versions for anyone who chooses to use Multisim software. If you do not have Multisim software and wish to purchase it in order to use these files, go to www.prenhall.com/ewb.
