Anotation:
The course describes the basic methods of analysis of electrical circuits. In the lectures, students are introduced to the basic active and passive circuit elements, circuit quantities, important circuit theorems and methods of circuit analysis in stationary and harmonic steady state as well as during transients caused by changes in the circuit. The seminars are aimed at practicing knowledge in the analysis of basic electrical circuits, supplemented by simulations and simple measurements.
