Learning outcomes
|
The aim of the course Linear Electric Circuits is to add more detailed and basic knowledge of electricity to the knowledge gained from other courses, namely the course of basic electricity (theory of electricity).
After the study of this subject the student will have more deep knowledge of the fundamentals of electricity. Namely the student will be able to solve electric circuits with direct, alternating (sine-wave) and general form voltage and current sources, calculate electric power and work (energy) in one-phase and three-phase electric networks, will have a basic knowledge about two-ports, filters, etc.
