Course abstract
When studying a course, students acquire knowledge of the theoretical bases of electrical knowledge: familiarity with linear DC circuits and techniques for calculating electrical circuits, non-linear DC circuits, their characteristics, applications and calculations, looks at magnetic circuits, their breakdown, materials, calculations. The physical nature of the sinusoidal current and its characteristics. Methods for calculating alternating circuits - the symbolic calculation method, vector chart
Learning outcomes and their assessment
Knowledge - of the theoretical fundamentals of electrical engineering and the theory of calculation of electrical circuits is understanding of physical processes in electrical circuits – test.
Skills - to perform electrical calculations - test. Kompetence - ability to calculate and evaluate the operation of electrical circuits - test.
