Answer:
Commutator is the device which is used to reverse the direction of current in the coil of a motor.
Explanation:
A commutator is a device which is used in directional machines and some other devices that are used to change the direction of electric current. In fact, together with the brush, it works as a rotary electrical switch. The commutator is made of hard curved copper. The hard-converter can convert such current into DC current and DC current into such current.
