Anotace:

The course introduces basic concepts of electrical circuits theory, defines

circuit values (variables) and circuit elements. It deals with the linear

resistive circuit analysis, and linear RLC circuit analysis in sinusoidal

steady state based on the symbolic-complex method (phasors, complex

impedances and admittances).

The basic priciples of elementary analysis are presented (Kirchhoff's laws,

voltage and current division, series and parallel element grouping, step by

step simplification method, transfiguration, Thévenin's and Norton's

theorem, superposition theorem). Basic topology concepts are defined and

general circuit analysis methods introducted (nodal voltage analysis, loop

current analysis) including their matrix form. The subject contents is

completed by DC and sinusoidal steady state power, resonance, phasor

diagrams and three-phase systems analysis.
