C)16
D)32

Question

Quizplus · Accepted Answer

The pole pitch is defined as the number of armature slots per pole. In a 4-pole machine, the total number of slots (or coils in this case) is divided by the number of poles to find the pole pitch. With 16 coils and 4 poles, the pole pitch is 16/4 = 4. However, since it's a two-layer winding, each slot contains 2 coils, effectively halving the number of slots to 8. Therefore, the pole pitch is 8.
