Electric circuit theory and electromagnetic theory are the two funda-
mental theories upon which all branches of electrical engineering are
built. Many branches of electrical engineering, such as power, electric
machines, control, electronics, communications, and instrumentation,
are based on electric circuit theory. Therefore, the basic electric circuit
theory course is the most important course for an electrical engineer-
ing student, and always an excellent starting point for a beginning stu-
dent in electrical engineering education. Circuit theory is also valuable
to students specializing in other branches of the physical sciences
because circuits are a good model for the study of energy systems in
general, and because of the applied mathematics, physics, and topol-
ogy involved
