Lap winding is called complete winding. After completion of the winding, all the slots are filled up with armature winding i.e. no slot is left empty.
In a lap winding
no of parallel paths = no. of poles = no. of brushes
In a wave winding
no. of parallel path = 2
= no. of poles for large current wave round machine.
Suppose, a 4 pole lap wound DC machine has armature current as Ia then, current in each armature coil is \(\rm \frac{I_a}{4}\)
Therefore, the correct option is (c).
