A DC generator armature has 6 poles and is lap wound. The number of brushes required are
- 2.
- 3.
- 6.
Explanation
A lap winding has as many parallel paths as poles, and therefore needs one brush set per pole. A six-pole lap-wound machine thus requires six brushes, in contrast to a wave winding which needs only two.

If the slip ring turns why e need 6 brushes, and why 2 isn't enough?

Each pole needs to have 1 brush so 6 poles = 6 brushes
