    The goalThe goal of the subject is to introduce student to characteristics and properties of materials employed in electrotechnics.The course includes electric materials, conductive materials, semiconductor materials, dielectric materials and magnetic materials.
    The outcomeStudents are introduced to characteristics and properties of materials employed in electrotechnics such as electric materials, conductive materials, semiconductor materials, dielectric materials and magnetic materials. By the end of the course students are capable of determining energy gap of semiconductors, transport characteristics of semiconductors, dielectric properties of insulator materials and magnetic characteristics od semiconductors and superconductors.
