Course detail

# Electrical Engineering 2

The course deals with the basics of electrical engineering and extends the knowledge obtained in the course BPA-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.

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.

Pravidla hodnocení a ukončení předmětu

Total number of points is 100, including 30 points in written tests in exercises, and 70 points for final exam. All laboratory measurements are obligatory - to obtain examination it is necessary to measure all of laboratory exercises and to obtain 15 points from maximum 30. Requirements for completion of a course are: to gain examination and to perform a written final test. Minimal necessary achieved total mark to pass this course is 50 points.
Attendance at laboratory classes is mandatory. Properly excused absences can be substituted, usually in the last week of the semester.

Učební cíle

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.
