The terminal voltage of a D.C. shunt generator drops on load because of all of the following reasons except
A)armature reaction
B)armature resistance drop
C)field weakening due to armature reaction and armature
D)commut ation

Question

Quizplus · Accepted Answer

Commutation in a DC generator primarily affects the quality of the current being produced rather than causing a drop in terminal voltage. It is related to the switching of current direction within the generator's armature windings and can lead to sparking at the brushes if not properly managed. The other options directly contribute to a drop in terminal voltage under load conditions.
