Summary
Theoretical Electrical Engineering deals with the analysis of electrical circuits because they are the most characteristic structure of electrical engineering. Knowledge of the theory of electrical circuits is one of the basic knowledge used throughout the course of study. Thesis: Basic principles and methods of alternating electrical circuits (Kirchhoff's laws, Ohm's law, principle of superposition, Thevenin and Norton theorem, law of continuity, Faraday's law), linear electronic components (resistor, inductor, capacitor) frequency characteristics, solution of transient processes I and II. order, Laplace's transformation. Homogeneous line, primary and secondary parameters, wave impedance.
Learning Outcomes of the Course Unit
The aim of the course is to teach students in a creative way to apply physical laws and principles in the analysis of phenomena in the electromagnetic field - stationary, non-stationary and electromagnetic waves and their dissemination. Circuit analysis in AC and DC circuits with linear elements. After education the subject of Theoretical Electrical Engineering, the student can analyze the currents, voltages, outputs and energy anywhere in the circuit and, on the basis of these, assess the properties of electrical equipment. The acquired knowledge and skills will be effectively applied by the student in practice.
