Course detail
Electrical Engineering 1
FEKT-BPC-EL1Acad. year: 2023/2024
The course deals with the basics of electrical engineering and in particular the theory of electrical circuits. At the beginning of the course universal and special methods of analysis of linear circuits in steady state are discussed. Next, students are introduced to the description and classification of time-varying quantities. The following part is an introduction to the analysis of nonlinear circuits using graphical and numerical methods. Another part of the course is dedicated to magnetic circuits, their description and basic methods of solutions, including circuits with permanent magnets. Important part of the course is laboratory exercises and computer exercises in which students will practice in the application of theoretical knowledge.

Entry knowledge
The subject knowledge on the secondary school level is required. In the range of the used mathematical tools students should be able to:
- editing mathematical expressions;
- explain the procedure of mathematical function examination in order to find extremes;
- calculate the solution of simple linear equations ;
- apply the basics of matrix calculus;
- calculate the derivative, definite and indefinite integrals of simple linear functions of one variable and basic trigonometric functions.
Work in the laboratory is subject to a valid "instructed person" qualification, which students must obtain before starting the course. Information on this qualification is provided in the Dean's Guideline on Student Familiarity with Safety Regulations.
Rules for evaluation and completion of the course
The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.
Aims
After completing the course student will be able to:
- describe the characteristics of electrical circuit elements and their models,
- apply basic circuit laws in the analysis of electrical circuits,
- analyze linear and nonlinear nonconservative electric circuits,
- interpret the quantities in electriccircuits,
- interpret the quantities in magnetic circuits,
- calculate the characteristic values of the time-varying voltage and current waveforms.
