The aim of the course is to acquaint students with
materials for electrical and electronic engineering,
with their classification an with their important
properties. This information enable the basic orientation in the selection of materials for constructions
of electrotechnical and electronic devices and equipments.
The aim in the part "Technical Documentation" is to acquaint students with standardization of documents in elektrotechnology, with ways and demands on their processing. The students will learn the basis of usage of CAD systems, MS Word and Excel.

Obligatory participation in teaching.
