In case of D.C. shunt motors the speed is dependent on back e.m.f. only because
A)back e.m.f. is equal to armature drop
B)armature drop is negligible
C)flux is proportional to armature current
D)flux is practically constant in D:C. shunt motors

Question

Quizplus · Accepted Answer

In D.C. shunt motors, the field winding is connected in parallel with the armature, resulting in a nearly constant field flux regardless of variations in the load. This constant flux means that the speed of the motor is primarily determined by the back electromotive force (e.m.f.), which opposes the applied voltage and is directly related to the motor's speed.
