FEATURES OF USING THE “LINEAR ELECTRIC CIRCUITS” PANEL OF THE STAND «ELECTRICAL ENGINEERING. FUNDAMENTALS OF ELECTRONICS UTLE-01» FOR EXPERIMENTAL VERIFICATION OF THE PRINCIPLE OF CURRENT IMPOSITION

Abstract

Electrical engineering refers to the field of science and technology that uses electrical and magnetic phenomena for practical purposes. The development of electrical engineering has always determined the close relationship of scientific and technical problems with social, economic, environmental and other tasks of society. Considering this, sufficient attention should be paid to the study of this discipline. When studying the Electrical Engineering course in institutions of higher education, a special place is occupied by calculations of branched electric circuits of direct current. Such circuits may contain several power sources, circuits, nodes, branches, the distribution of currents along which must be determined. The theory of electric circuits provides several methods for solving such a problem, one of which is the principle of superimposing currents. The essence of this principle is that the current in the line of a branched circuit is equal to the algebraic sum of the partial currents that arise in it from the independent action of each source separately. That is, each source contributes its share to the total line current, and to find this current, you need to algebraically add the components of these currents. The calculation of partial currents is usually carried out by transforming the scheme. Therefore, the solution of one complex circle is reduced to several simple circles that contain one source. The article analyzes the features of using the panel of the domestic manufacturer "Linear Electric Circuits", which is part of the "Electrical Engineering" stand. Basics of electronics UTLE-01" for experimental verification of the principle of superposition of currents during laboratory work from the Electrical Engineering course. Methodological guidelines for performing such work with table layouts for entering research results have been developed. Also, for a better understanding of the principle of superposition of currents, a theoretical problem with its detailed analysis and solution is considered. Such an approach of combining theoretical calculations with experimental research contributes to a better understanding by students of the subject under consideration and contributes to their acquisition of the necessary professional competences.
