Elektrotehnika 1. stopnja

Objectives and competences

To acquire fundamental knowledge on magnetic field, induced field as well as AC electric circuits, three phase systems and transient circuit analysis. The acquired knowledge serves as a basis for further electrotechnical studies.

Learning and teaching methods

Lectures, exercises, laboratory work (practicum), homeworks and seminars, IT assisted teaching (video, animations, web materials, simulation examples, …)

Intended learning outcomes

After successful completion of the course, students should be able to:

– define basic quantities, units and constants from the field of electrotehnics and explain their meaning,

– explain the relations between quantities, perform analytical calculations and interpret the results,

– study and understand the instructions for practical experiments from the field of electrotehnics, perform laboratory experiments and evaluate the results.
