COURSE OBJECTIVES: To provide an introduction to sophomores in the field of electrical engineering to the fundamental concepts in the sub-area of electrical circuits. This course will be one of five fundamentals courses required of all electrical engineering majors. Another objective is to prepare students to take some more advanced courses in the area of circuits and electronics.
