Subject specific learning outcomes and competences

Ability to analyse electric circuits with practical application in computer science.
Knowledge of safety regulations for work with electronic devices.

Learning objectives

To obtain general knowledge and basics of selected methods of description and analysis of electric circuits with practical application in computer science. To obtain detailed instructions and information about occupational safety with electric devices. To gain practical knowledge of working with fundamental electronic circuits in labs.

Why is the course taught

Even though the software is immaterial, the humanity has to still use matter to express and store thoughts, ideas and solutions. Systems designed to store the information are very complicated and have to be miniaturized. And because everything is still made of matter, we need forces that can manipulate even small particles of matter. Electromagnetic fields contain such sources, so we can, using smartly designed circuits, focus the energy and manipulate it very precisely. This is why computers are based on electronics. To understand how the computers work, we need to understand basic laws that govern electric field, electric circuits. This knowledge can then be useful when designing more complicated (for the most part digital) electronic circuits. 

Prerequisite kwnowledge and skills

This course takes place in the winter term of the first year of the bachelor's study programme. Thus, we expect that students have the high school level knowledge.

  4. Transient events in RLC circuits

Progress assessment

During the semester, 6 laboratories (each for a maximum of 3 points), semestral project (max. 12 points) and mid semester exam (maximum 15 points) are assessed.

Controlled instruction

Mid-term exam and Final exam: The minimal number of points which can be obtained from the final exam is 27. Otherwise, no points will be assigned to a student. Laboratories are voluntary. The missed laboratory is possible to replace with the individual project after consultation with the lecturer.

Exam prerequisites

  • The necessity of complete an electrical safety training course (compliant with Decree No 50/1978)
  • Obtain at least 3 points from the semester project and at least 6 points from laboratories.
