The subject of electrical engineering and electronics takes up the previous study and deepens and extends the knowledge in the aforementioned field. Emphasis is laid on the practical application of theoretical knowledge in laboratories.

Knowledge in mathematics and physics in a scope of the study at Faculty of Mechanical Engineering is expected.

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

The subject is completed with the credit and the examination. To gain the credit, the conditions and requirements prescribed at the tutorial beginning must be met, i.e. compulsory attendance in laboratory, exercise preparation, all protocols processed and submitted in time and accepted by the teacher. The teacher can verify the student’s preparedness at each tutorial beginning. The examination is based on a written test, and the student may achieve the scoring of up to 100. The final scoring rate of the test shall be classified according to the ECTS grading system.

The objective of the subject is to familiarize the students with the principles of the advanced electrical engineering which are necessary for the study of other mechanical engineering disciplines, and mainly to be skill in technical practice.

The presence of the students in laboratories shall be checked during the semester and each laboratory report shall be scored. In case of regularly apologized student’s absence in the laboratory practice, the student may attend the laboratory practice together with other student team if agreed with the lecturer, or again in case of an apologized absence to participate in the alternative laboratory practice at the end of the semester.
