THE USE OF PRACTICAL AND LABORATORY CLASSES IN THE STUDY OF COMPLEX LINEAR ELECTRIC CIRCUITS OF DIRECT CURRENT IN THE COURSE OF ELECTRICAL ENGINEERING

Abstract

The relevance of obtaining theoretical knowledge and practical skills by students of higher education when studying electrical engineering in higher educational institutions for the calculation of complex electric circuits containing several nodes, branches, and contours is considered. Such knowledge is necessary for specialists working in the field of information technology, energy, industrial production or just in everyday life and can be used for the correct operation of various electrical installations. In particular, the article analyzes the peculiarities of studying complex linear electric circuits of direct current in the course “Electrical Engineering” in practical and laboratory classes. The calculation of the currents in the circuits of the electric circuit was carried out on the basis of Kirchhoff’s first and second laws. The calculation method for an electric circuit containing two independent circuits, three EMF sources and three different resistances is considered in detail. Compound equations for independent circuits are proposed to be written in matrix form, which greatly simplifies the finding of unknown currents. Emphasis is placed on the need to conduct laboratory work when studying electrical engineering for a better understanding of new material by students. Today on the market there is an opportunity to buy a variety of laboratory equipment, but the manufacturer, as a rule, does not give methodological instructions for conducting laboratory work. Therefore, there is a need to do it yourself. In this regard, the use of “Linear electric circuits” panels of the domestic manufacturer during the performance of laboratory work on electrical engineering to acquire practical skills in the study of complex electric circuits is substantiated. Theoretical information for the laboratory work “Experimental verification of Kirchhoff’s laws” has been developed, which can be effectively used in classes with students of higher educational institutions. The combination of theory and developed laboratory work will allow students to learn not only to correctly perform theoretical calculations, but also to make branched circles, to make the necessary measurements, which will help to acquire the necessary professional competences of the future specialist.
