F7ABBTEL - Theory of Electrical Engineering

11.2.2026 - In the summer semester 2025/2026, 10 exercises are planned in computer room B-435 and 2 exercises in laboratory A-11 (weeks 13, 14), where the selected exercises will be measured. When creating the schedule, it is necessary to register for both the exercises in the PC classroom B-435 and the laboratory measurements in room A-11. Only exercises or laboratory measurements will take place in each week.
