### Description

Version: 7.0 start 01 February 2024

#### Short description

This course is one of the fundamental technical courses. It consists of theoretical (lectures) and practical parts (laboratory experiments). Students learn the physical and technical fundaments of AC (Alternating Current) circuit theory (including three-phase systems and one-port circuit elements) and the frequency-dependent behaviour of electrical circuits and networks. They also gain an understanding of the real behaviour of the key components of AC circuits and related phenomena, like the skin effect etc.

#### Learning objectives (competencies)

 Objectives Competences Taxonomy levels Students know the mathematical principles of alternating current and three-phase electric power systems. They know the properties of AC and the AC behaviour of real linear one-port electrical elements; they can explain the physical principles and carry out calculation tasks with phasors. F, M K1, K2, K3 Students understand the fundamentals of the three phase systems and they can solve numerical examples with symmetrical und unsymmetrical loads in 3 and 4 wire AC-systems. F, M K1, K2, K3 They are able to measure and understand the meaning of the electrical quantities such as: Impedance, admittance, etc. AC electric power (active, reactive and apparent) Frequency behaviour of real elements in RLC circuits F, M K3 Students are familiar with frequency characteristics of the AC circuits (they can draw, calculate and analyse the corresponding Bode plot and transfer functions) F, M K3, K4
