Q. 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

Answer: flux is practically constant in D:C. shunt motors
