Learning outcomes
|
The course is an introduction to the study of analysis and synthesis of electrical circuits.
By studying the course the student will gain deeper knowledge of the basics of electrical engineering, in particular he will learn to solve electrical circuits for DC, sinusoidal and general voltages and currents, determine the power and work done by electric current (in single-phase and three-phase network), gain basic knowledge of double gates and their parameters, filters.
