What is used to polish commutators or slip rings?

Double-0 sandpaper
Stiff bristle brushes
Emery cloths
Wet cloth

The correct answer is: Double-0 sandpaper

Double-0 sandpaper is the best option for polishing commutators or slip rings. This is because it is specifically designed for this purpose and provides a smooth and consistent finish. Option B, stiff bristle brushes, may not be as effective as they can leave behind bristles that can interfere with the proper functioning of the commutator. Option C, emery cloths, may be too harsh and abrasive for delicate commutators, leading to damage. Option D, a wet cloth, is not suitable as it can cause the commutator to rust.
