  • (B)  has a poor torque
  • (C)  can be started easily without load
  • (D)  has almost constant speed
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
