Course detail

# Electrical Engineering

FEKT-HELEAcad. year: 2020/2021

The course deals with the basics of electrical engineering and in particular the theory of electrical circuits. At the beginning of the course the historical evolution of electrical engineering is discussed, followed by an introduction to the analysis of linear circuits in steady and harmonic steady state, including three-phase system. Another parts of the course are dedicated to magnetic circuits and the theory of homogeneous transmission line. Important part of the course is laboratory exercises and computational tasks in which students will practice in the application of theoretical knowledge. Laboratory and computational exercises always logically follows the lectures. Emphasis is placed on the linguistic part of the course, when all course materials are in English.

Learning outcomes of the course unit

After completion of the course (lectures and computer exercises) student will be able to:

- mathematically express relations between circuit quantities for basic passive and active circuit elements and to define their models;

- apply the basic analysis methods of linear circuits in stationary steady;

- calculate the characteristic parameters of time-varying signals and to describe the principle of harmonic analysis of signals;

- define phasor quantities in circuits in harmonic steady state and to define immittance parameters of basic circuit elements;

- apply symbolic method for analysis of linear circuits in harmonic steady state;

- list the fundamental variables and the laws of magnetic circuits and to calculate the parameters of magnetic circuit by their utilization;

- describe the parameters of transmission lines and explain the importance of secondary line parameters.

In terms of language skills, students will be able to describe the above knowledge in English and will be equipped with the appropriate technical terminology.

Prerequisites

English language knowledge on pre-intermediate level are required. In the range of the used mathematics student should be able to:
- editing of the mathematical expressions;

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Teachning methods include lectures and seminars. Course is taking advantage of e-learning (Moodle) system.

Assesment methods and criteria linked to learning outcomes

The exam will take place online.

Total number of points is 100. During the semester, the student may obtain up to 40 points for 4 written tests, each 10 points. Tests are carried out on seminars and always consist of examples and theoretical questions.

The requirement for examination obtaining is the completed measurement of all laboratory tasks, elaborated computational exercises and to obtain minimally 15 points from written tests. Moreover, subject to the successful completion of the course is to pass the final exam. The total number of points achieved for completion of the course must be at least 50.

The tests and final exam verify students’ orientation in the problems of the foundations of analysis of electric and magnetic circuits, knowledge of technical terminology and the ability to describe in their own words the topics covered in the course. Test assignments, laboratory exercises, final exams are in the English language.
