Modern simulation programs provide a good opportunity to conduct exper-imental studies of electric circuits of various voltages and without costs and damages. The MULTISIM practical program is one of the computer programs for simulating the operation of electrical circuits. In this work, the structure and properties of the simulation of simple electri-cal circuits in the database of the electronic laboratory are presented. The use of the Multisim44program as an aid to checking the results of manual calculations is discussed in the example of the analysis of parallel series of electrical circuits. At the initial stage of mastering the methods of designing and testing the model of electronic structures, the use of the program NI Multisim 14, which contains a large number of electronic components, is very convenient for simulation. The MS14 environment is characterized by the presence of control-measuring instruments, as well as the appearance and characteristics of industrial instruments. The large number and va-riety of analog, digital, and mixed analog-digital architectures, analysis tools, and virtual in-struments make the MS14 environment a very convenient tool for reflecting and demonstrating fundamental phenomena and processes in analog and digital electronics. In order to create more complex structures, the modular principle is used, that is, complex structures are created from simple circuits consisting of resistors, capacitors, diodes, transistors, logic elements, op-erational amplifiers and digital chips.
