Course detail

# Electrical Engineering 2

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

Learning outcomes of the course unit

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.
