Aims

The aim of the course is to acquaint students with materials for electrical and electronic engineering, with their classification and with their important properties. This information enables basic orientation in selection of materials for constructions of electrotechnical and electronic devices and equipments.
At the end of the course, the student will be able to:
- be knowledgeable in electronic and electrical materials,
- classify electrical materials according to electric conductivity and behavior in electric and magnetic fields,
- describe typical properties and parameters of particular categories of electrical materials and links between these properties and material structure and composition,
