Prerequisites
Co-requisites
Planned learning activities and teaching methods
Assesment methods and criteria linked to learning outcomes
Students can obtain:
up to 40 points from tutorial lessons (tests and protocols from laboratory exercise)
up to 60 points from the exam (30 points practical part and 30 points theoretical part), both parts are in the written form. The exam is focused to verify the student understanding of the area power distribution.
Detailed requirements for completion of a course are specified by a regulation issued by the lecturer responsible for the course and updated every year.
