Electric Circuits is the most widely used introductory circuits textbook of the past decade. The book has remained popular due to its success in implementing three themes throughout the text: (1) It builds an understanding of concepts based on information the student has previously learned; (2) The text helps stress the relationship between conceptual understanding and problem-solving approaches; (3) The authors provide numerous examples and problems that use realistic values and situations to give students a strong foundation of engineering practice.
