Aims

The provable instructions of students from safety rules necessary for the laboratory exercises and verification according to the notice No. 50/1978. Offering basic knowledge of electrical engineering and circuit theory needed as a
wider scientific basis of further study. To prepare the students for following courses of specialization in electrical engineering. Numerical exercises extend and improve theoretical knowledge, laboratory measurements help to verify some theory in a practical way.

Specification of controlled education, way of implementation and compensation for absences

The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.
