Summary
Aim of the subject is to give the learner essential theoretical and practical knowledge from areas of electrotechnical materials.Aquired knowledge allows students right selection from electrotechnical materials during construction and projection of electrotechnical and electronical.
Purporse of the study is to give the learner essential theoretical and practical knowledge from areas of electrotechnical materials. During the practical part students measure tasks from areas of insulating materials, conducting materials, magnetic materials, semiconducting materials and structures.
