b. A transformer uses a commutator to step up voltage
c. A motor uses a commutator to reverse the current

Answer 1

Hey mate, here is your answer ===

A motor uses a commutator to reverse the current.

Hope it helps u dear :)

Answer 2

A motor uses a commutator to reverse the current

Explanation:

• Commutator is a device that is used to reverse the flow of current in the motor.
• It is like a connection, associated with the armature of a motor or dynamo, through which electrical association is made and which guarantees the flow of current.
• To keep the torque on a motor from turning around each time the loop travels through the plane opposite to the attractive field, a commutator is utilized to invert the current.
• Gadgets such as galvanometer and transformer don't use commutator as a device.
