Abstract. The course "Electrical Engineering and Electronics’" is an important component of training modern specialists in machine-building in the cycle of general professional disciplines established by the state educational standard of higher professional education. Operational amplifiers (OA) in the integrated circuit form, which are studied in this course, are one of the basic elements of analogous electronic devices. The article proposes methodology to conduct practical study on OA characteristics and operating regimes in Multisim 10.1 environment that allows students to acquire practical skills in using these devices and to deepen their theoretical knowledge in this sphere.
