Subject aims expressed by acquired skills and competences
Cílem předmětu je naučit studenty tvůrčím způsobem aplikovat fyzikální zákony a principy při analýze střídavých a stejnosměrných lineárních a nelineárních obvodů. Poznatky z teorie obvodů patří mezi základní znalosti, které student uplatní v celém průběhu studia. Po absolvování výuky předmětu Teorie obvodů I umí student vypočítat proudy, napětí, výkony a energie kdekoliv v obvodu a na jejich základě posuzovat vlastnosti elektrických zařízení.
Teaching methods
Summary
The course "Theoretical electrical engineering I" deals with the analysis of the electrical circuits - the most typical structure in the electrical engineering. Electrical circuits knowledge are basic knowledge and they are a prerequisite for advanced circuit courses (electronic, measuring and control systems, electrical machines, etc.).
The basic aim is to determine voltages and currents in the electrical circuit, and then identify (from these knowledge) the properties of the circuit or system. Theses: elementary models of electromagnetic effects, circuit analysis algorithms, transients in the linear circuits (the 1. order), experimental measurements (Associate professor Josef Punčochář).
