The correct answer is: A. Slots<\/p>\n
A commutator is a cylindrical device with a series of metal bars (commutator bars) insulated from each other and from the cylinder. The commutator is used to reverse the current in the armature windings of a DC motor or generator.<\/p>\n
The number of commutator bars is equal to the number of slots in the armature. This is because the commutator bars are located in the slots, and the brushes of the motor or generator make contact with the commutator bars.<\/p>\n
The number of armature conductors is equal to the number of commutator bars plus one. This is because there is one armature conductor for each commutator bar, and one additional armature conductor that connects the two ends of the armature winding.<\/p>\n
The number of winding elements is equal to the number of armature conductors divided by the number of poles. This is because each winding element consists of one armature conductor from each pole.<\/p>\n
