After successfully completing this course, students will have acquired the basic electrotechnical knowledge required for all areas of specialization in the study program and be familiar with analysis methods for magnetic fields, as well as the alternating current and three-phase current theory. I.e. they will be able to carry out calculations with the respective physical formulas and quantities and derive useful solutions, as well as make calculations for tasks given in this field based on common physical-mathematical laws, in particular with the help of complex numbers. They will be familiar with the analogies between flow, electric and magnetic fields, and thus, be capable of determining the field pattern and the way it is fundamentally influenced by shapes and materials for frequently occurring geometries. They will also be able to design magnetic circuits. Students will be able to carry out computational and metrological analyses on and make layouts of AC and three-wire circuits that are new to them, as well as dimension components. Thanks to the experiments carried out in the lab class, students will have experience in teamwork, time management and working independently. The experiments are designed as small projects and carried out in small groups.
