Course detail
Electrical Engineering 2
FEKT-BKC-EL2Acad. year: 2022/2023
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.
