Course objective is to teach students about basic physical parameters of the loads in electric circuits, such as resistance of resistors, inductance of coils and capacitance of capacitors. Goal of course is to teach students to solve simple electric circuits of direct current and time variable currents, as well as to calculate impedance in second case. Also, the objective is to teach the students how to solve single phase circuits as well as simple balanced three-phase circuits. Introduction of electric power in single and three phase electrical circuits.

Students who successfully complete the course will be able to calculate capacitance of a simple homogeneous symmetric structure, to calculate resistance of homogeneous multilayer structure, to solve simple electric circuit of direct current, to calculate magnetic field of simple symmetrical current caring structures, to calculate inductance of simple structures with windings, to solve simple electric and magnetic fields with simple alternating currents and to calculate instantaneous, active, reactive and apparent power in single phase and balanced three phase circuits.
