As a motor armature turns faster and faster, net current in the motor windings
A) increases.
B) decreases.
C) remains unchanged.

Question

Quizplus · Accepted Answer

As the motor armature turns faster, the back EMF (electromotive force) generated by the motor increases. This back EMF opposes the applied voltage, effectively reducing the net voltage across the motor windings, which in turn reduces the current through the motor according to Ohm's law (V = IR).
