Course detail
Electrical Engineering and Electronics
FSI-CEL Acad. year: 2021/2022 Winter semester
The subject is focused on the principles of electrical and electronic circuits, electrical machines and electrical drives in a scope of a bachelor study at faculties of mechanical engineering. Attention is devoted to the theory of electrical measurements and safety at work. Special attention is laid on laboratories where the students shall apply their theoretical knowledge in practice.

Learning outcomes of the course unit
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.
Prerequisites
Knowledge in mathematics and physics in a scope of the study at Faculty of Mechanical Engineering is expected.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
The course is completed by credit and exam.
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. At the beginning of the exercise, the teacher can check the readiness of the students for exercise. Furthermore, it is necessary to obtain at least half the number of points from the control tests. A maximum of 20 points that are part of the overall classification can be obtained from the control tests.
The exam is realized by a written test consisting of a theoretical part and a part with examples. The student can get up to 80 points from the exam.
Evaluation of the test result is given by the ECTS grading scale.
Aims
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.
Specification of controlled education, way of implementation and compensation for absences
The presence of the students in laboratories shall be checked during the semester and each laboratory report shall be scored. Laboratories are required. 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.
