Learning outcomes
|
This course is an introduction to the study of electrical engineering. First, the basic concepts of electrical engineering are introduced, followed by the problems of electromagnetic wave propagation along lines and in free space.
After completing the course, the student is able to orientate in electromagnetism, Maxwell's equations and problems of wave propagation. The student is able to analyze DC and AC circuits, linear and nonlinear, in steady state and transient for single phase + three phase power networks, transient characteristics, frequency and transmission characteristics, and characteristics of double gates, feedback and electrical filters.
