GS&EI ElectEngg 14 2024 1601-2025 The armature resistance changes when the winding is converted from lap to wave due to the change in the number of parallel paths and the number of conductors in series per path. For a lap winding, the resistance is inversely proportional to $P^2$, while for a wave winding, it is inversely proportional to 4 (a constant).
A 6-pole lap wound DC machine has an armature resistance of 0.06 Ω. If the machine is rewound for wave winding, then its armature resistance is
