Current field, Ohm’s law, Joule’s law, specific electric conductivity, boundary conditions of current field, resistance and conductance, grounding resistance, resistor, non-linear resistor, voltage-current characteristic. Voltage and current sources, DC electric circuits, analyses and theorems. 

To acquire fundamental knowledge on electrostatic field, current field and DC electric circuits.

The acquired knowledge serves as a basis for further electrotechnical studies.

Lectures are used to teach students the basic theory of electrical engineering from the course Content and use additional practical examples to elaborate on it. In lectures also demonstration experiments are used together with computer animations. Some computer tools are presented that are used in computation and visualization of electric fields.

At the tutorials (exercises) the students elaborate further the problems by solving specific tasks / cases with analytical solutions.

Laboratory exercises include preparations where students get acquainted with work to be performed in a laboratory, homework, where students independently solve the pre-prepared case and additional literature studies and experimental work in the laboratory, where they prepare experiments according to the instructions and describe the experimental results.
