Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

E505 Electrical Engineering, Bachelor, ASPO 01.10.2005 , semester 5, mandatory course
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
45 class hours (= 33.75 clock hours) over a 15-week period.
The total student study time is 120 hours (equivalent to 4 ECTS credits).
There are therefore 86.25 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
E303 Electronics I
E405 Electrical Machines I
