Abstract. Several features of constructing concentric conductive rings using rolling elements, which are planned to be used as structures like rolling bearings, are described. Such a design is reported to have advantages over sliding elements, including a large service life, high rotation speed, and low drag moment. The reasons for the occurrence of electrical noise in working slip rings are considered in detail using the example of electrical circuits containing resistors connected in parallel. Using the example of the investigated electrical circuit, to which a pair of contacts is added, the dependence of the resistance value in the slip rings on the number of contacts connected to them is determined.
Keywords: slip ring, contact ring, sliding contacts, electrical noise, resistors, resistance
