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

Total number of points is 100, including 25 points in two written tests in exercises, 5 points in laboratory tasks test and 70 points in final exam. All laboratory measurements are obligatory - to obtain examination it is necessary to measure all of laboratory exercises and to obtain 15 from maximum 30 points. Requirements for completion of a course are: to gain examination and to perform a final written test. Minimal necessary achieved total mark to pass this course is 50 points.
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

The aim of the course is to provide basic knowledge of electrical circuit theory required as a broader basis for further study. The course prepares students for the following courses in electrical engineering specializations.
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.
