Within the study course, the student will learn linear electric circuits basic concepts and laws. The main methods of circuit calculation and analysis, various calculation methods, application of theory in circuit calculations are mastered. The study course explains how to analyse circuits that have direct current or voltage sources. The study course provides insight into the application of circuit simulator SPICE software LTSpice and MATLAB in circuit calculations.
The acquired knowledge is essential for the acquisition of further study courses.
