C) cease
D) stay the same

Question

Quizplus · Accepted Answer

As the speed of a series-wound motor increases, the torque output of the motor will decrease. This is because the increased speed causes increased counter-EMF (electromotive force) which reduces the net voltage across the armature windings and ultimately reduces the motor's torque output.
