| What statement is true concerning the use of commutating poles (also known as interpoles) in DC generators? |
| A) These large poles are placed in the magnetic neutral plane between the main field poles and are designed to eliminate or reduce sparking caused by inductance of the field coils. |
| B) These windings are wound on the main field poles and are designed to eliminate or reduce sparking caused by inductance of the field coils. |
| C) These windings are wound on the main field poles and are designed to eliminate or reduce sparking caused by inductance of the armature coils. |
| D) These narrow poles are placed in the magnetic neutral plane between the main field poles and are designed to eliminate or reduce sparking caused by inductance of the armature coils. |
