Question

Quizplus · Accepted Answer

The device that provides a surface on which the brush assembly makes electrical contact in a DC generator is a commutator. The commutator is a cylindrical structure that is attached to the armature and has a series of copper segments that are insulated from each other. The brush assembly is comprised of carbon brushes that rub against the commutator to provide electrical contact. The commutator helps to change the direction of the current in the armature coils as the rotor rotates, which is necessary for generating a continuous DC output.
