Forms of Teaching

Lectures

Material is tought using Power point presentation and blackboard. Lectures are organized together with laboratory exercises. Lectures also include auditory excercises. Using Moodle system students also solve domestic exercises.

Laboratory

The goal is to introduce electrical components and present measurement equipment and measurement procedures. Individual practical experience in laboratory in applying the concepts that are taught in lectures.
