Course detail

Electrical Engineering 1

FEKT-KEL1Acad. year: 2018/2019

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. During the course the students are familiarized with the safety regulations necessary for laboratory teaching.

- 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 electrical circuits,
- calculate the characteristic values of the time-varying voltage and current waveforms.

Prerequisites

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.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teachning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Student works out lab reports in the workbook (available in print and electronic form).

Assesment methods and criteria linked to learning outcomes

Total number of points is 100, including 30 points in the individual works (5 works for up to 6 points), and 70 points in final exam. Students have to submit all 5 individual works and obtain at least 15 points from 30 possible, as well as active participation in both exercises. 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.
