Learning outcomes
Knowledge of electrical quantities and units involved in the study of circuits; knowledge of linear one-port systems and their energy properties; knowledge of circuit laws and their numerical implementation; ability to solve simple circuit problems in DC and AC. Knowledge of magnetic fields in quasi-static conditions, electric machines and safety.
Course contents
DC circuits
Basic electrical quantities. One-port systems and their voltage-current characteristic. Ohm’s law. Power balance. Electric circuits. Nodes and loops. Kirchhoff’s laws. Linear circuit analysis. Circuit theorems.

AC circuits
Capacitor. Inductor. Signals in the time-domain and their representation. Circuit analysis in the frequency domain. Phasors. Impedance and admittance. Real, imaginary and complex power.

Power circuits
Three-phase systems: definitions and basic properties. Symmetric and balanced systems. Three-phase generators and loads. Power in three-phase systems and its measurements.

Applications
Elements of electromechanical energy conversion. Transformer. Rotating machines: asynchronous, induction and d.c. machines. Electric power plants: generating plants, transmission and distribution systems. Voltage-drop and power losses in distribution systems. Load power factor correction. Switching and protective devices. Safety in electric installations.
Teaching methods
The lectures are held with the help of blackboard and slide based presentations. The slides are made available to students.
Numerical exercises and tutorials are organized too.
