Appropriate for introductory college courses in electrical engineering for major and nonmajors alike. Assumes that students have already completed one year of college-level calculus and physics. This text presents the basics of electrical engineering from the perspective of the primary principles behind the subject, rather than dwelling on superficial details. It is based on three objectives: to explain the fundamental ideas behind electrical engineering, to emphasize the unity of the subject, and to bring an understanding of the subject within the reach of all engineers.
