Answer:
we can increase the number of parallel paths by increasing the number of poles or number of brushes
Explanation:
In a lap winding, the number of parallel paths, a, is always equal to the number of poles, p, and also to the number of brushes. When two adjacent commutator bars make contact with a brush, one coil is shorted by the brush in the lap winding.
