Course objective is to teach students to solve simple electric circuits of direct current and time variable current, as well as to calculate impedance and basic physical parameters of the loads in such networks, resistance of resistors, inductance of coils and capacitance of capacitors. Also, the objective is that the students learn how to solve single phase circuits as well as simple symmetrical three-phase circuits.

Students who successfully complete the course are able to calculate currents and voltages in simple electric circuits of direct current, to calculate impedance of simple structures with windings, to solve simple electric circuits with alternating currents and to calculate instantaneous, active, reactive and apparent power in mono phase and symmetrical three phase circuits.
