Summary
The course "Circuit theory 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).
Learning Outcomes of the Course Unit
The aim of education is give creative lessons in physical laws and principles to analysis of three-phase circuit, transient phenomena, two-port network, frequency response and distributed lines. After education student is able to calculated current, voltage, power and energy in circuit anyplace and then on the basis of them look on properties of electrical device. Student practices obtained knowledge and acquirements energetically.
