Q. Starters are used with D.C. motors because

A.            these motors have high starting torque

B.            these motors are not self-starting

C.            back e.m.f. of these motors is zero initially

D.            to restrict armature current as there is no back e.m.f. while starting

Answer: to restrict armature current as there is no back e.m.f. while starting
