### Subject aims expressed by acquired skills and competences

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.

### Summary

Learning outcomes of the course unit The aim of the subject of Circuit Theory II is to teach students how to apply physics laws and principles in the analysis of elementary phenomena in three-phase circuits, transient phenomena, linear and nonlinear two-ports and distributed parameters. The knowledge of circuit theory is one of the basic knowledge that the student will apply throughout the course of study. After completing the subject of Circuit Theory II, the student is able to calculate the voltages and currents anywhere in the circuit and to assess the properties of the electrical devices.
