Due to which of the following reasons concentrated winding are not used in alternators ?
A. Concentrated windings increase voltage harmonics.
B. Concentrated windings decreases induced e.m.f./phase.
C. Concentrated windings increase copper-to-iron ratio thereby decreasing the capacity.
D. Concentrated winding require deep slots for accommodation which leads to increased armature leakage reactance.
