Course detail

Electrical Engineering 2

FEKT-BKC-EL2Acad. year: 2024/2025

The course deals with the basics of electrical engineering and extends the knowledge obtained in the course BKC-EL1. At the beginning of the course are discussed universal and special methods of analysis of linear circuits in harmonic steady state, including the polyphase circuits. In the next section, students learn about the characteristics of RC, RL and RLC circuits. The following part explain classical and operator method of transient solution in linear circuits, students will learn how to determine the response of the circuit to the standard and arbitrary signals. The last part of the course is theory of homogeneous transmission lines.

Entry knowledge

Student must for successful completion of the course manage the content of the course Electrical Engineering 1 and be able to:
- define the concepts of electrical resistance, capacitance and inductance;
- express in their own words the basic laws of electrical circuits and be able to explain the relationship between voltage and current at the fundamental elements R, L and C;
- use appropriate methods to analyze linear circuits;
- calculate the basic parameters of the time-varying signals;
- apply the methods of mathematical analysis calculations for systems of equations using matrix methods;
- use mathematics in the field of complex numbers;
- manage general calculate derivatives and integrals simple basic functions;
- calculate linear ordinary differential equations.

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 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. 


 

Aims

The course develops the knowledge gained in BEL1 (Electrical Engineering 1) and prepares the students for following courses of specializations in electrical engineering.
After completing the course student will be able to:
- define the terms in the field of circuit analysis in HUS as a phasor, complexor, impedance, admittance, etc., and to analyze linear electrical circuits in harmonic steady state;
- list the primary and secondary line parameters and explain the propagation of waves on transmission lines in the steady state and the transient;
- explain the behavior of RLC circuits, meaning of resonance response of the circuit;
- discuss the importance of three-phase distribution systems and distinguish the concepts associated with it;
- apply the Laplace transform to solve transients in linear circuits;
- calculate the response of a linear circuit on the basic input signals.
