## 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.
