Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Total number of points is 100, including 25 points in two written tests in exercises, 5 points for laboratory course test and 70 points for final exam. All laboratory measurements are obligatory - to obtain credit it is necessary to measure all of laboratory exercises and to obtain 15 points from maximum 30. Requirements for completion of a course are: to gain credit and to perform an exam. Minimal necessary achieved total mark to pass this course is 50 points.

Aims

The course develops the knowledge gained in EL1 (Electrical Engineering 1) in the 1st term of study and prepares the students for following courses of specializations in electrical engineering. Laboratory measurements and numerical exercises help in verifying theory taught in lectures. In last week students will be examined to obtain qualification level "competent worker".

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.
