Fundamentals of Electric Circuits continues in the spirit of its successful previous editions, with the objective of presenting circuit analysis in a manner that is clearer, more interesting, and easier to understand than other, more traditional texts. Students are introduced to the sound, six-step problem solving methodology in chapter one, and are consistently made to apply and practice these steps in practice problems and homework problems throughout the text. A balance of theory, worked & extended examples, practice problems, and real-world applications, combined with over 468 new or changed homework problems complete this edition. Robust media offerings, renders this text to be the most comprehensive and student-friendly approach to linear circuit analysis out there. This book retains the "Design a Problem" feature which helps students develop their design skills by having the student develop the question, as well as the solution. There are over 100 "Design a Problem" exercises integrated into problem sets in the book.
