Course abstract

Study course includes basic rules and characters of direct current, magnetic and alternative current electric circuits, the systems of electric measuring instruments and methods for measuring of electric and nonelectric quantities, conception about electric safety. During study course there are obtained principles of design and operation, working conditions, modifications and choice of transformers, asynchronous motors, DC motors, electric heat and lighting sources, lighting calculations, protection’s equipment.

Learning outcomes and their assessment

Knowledges: general electrical engineering bases, general electrical measurement techniques, general fundamentals of the design, operation and selection of electrical components for main manufacturing and craft products – tests No. 1 to 3, laboratory works;
Abilities: to perform simplified electrical equipment, its components and their working mode choice, choice of type of lighting and its key parameters, link them to the design of the product; tests No. 1 to 3, laboratory works;
Competencies: to assess the conformity of the type of electrical equipment, element or device and working modes with the conditions required for the product, the impact on the design and parameters of the product. - quality of performance of tests and laboratory works and the defence of laboratory works.

Requirements for awarding credit points

All tests must be credited, laboratory works must be worked and defended .
A lessons visit not less than 75%

Criteria for Evaluating Learning Outcomes

Credit is obtained by successfully writing all three tests and working and defending all laboratory works.
Test evaluation:
7 questions in each of the three tests.
Assessment: correct, complete answer to the specific question – 1 point, partial or non-essential errors - 0.5 points, incorrect or not - 0 point.
Minimum score for positive each test evaluation– 3.5 points.
