Electrical circuit and its elements. Ohm' s law. Resistivity. Computation of direct current electrical circuits. Work and power of direct current. Direct current generators and motors. Main characteristics of alternative current. Computation of alternative current electrical circuits at an active load.
Alternative current circuits at a capacity, inductive and active load.

.- to provide understanding about main concepts, their connection with electrical devices;
- to provide skills for computation of electric circuits with active load;
- to provide knowledge about the properties of single-phase alternative current, skills for computing them at capacity, inductive and active load;
- to provide basic knowledge about direct current electrical machines and their usage possibilities;
- to provide basic knowledge about three-phase alternative current and alternative current electrical machines;
- to provide knowledge about the basics of work of asynchronous motors, their construction and usage possibilities.

The student:
- knows the main elements of electrical engineering and their properties, direct current electrical motors and their construction and also physical basics of their work;
- can compute simpler electrical schemes of direct and single-phase alternative current;
- knows the properties of single- and three-phase alternative current and differences from direct current, can compute the electrical circuits of three-phase alternative current at active load;
- knows alternative current electrical machines with the main emphasis being on asynchronous motor: principles of their work, structural and usage possibilities, their control.

Lectures, exercise classes, tests, laboratory works, written prelim paper.
