As a DC motor armature starts to rotate, the CEMF increases and the line current decreases.

Question

Quizplus · Accepted Answer

As the armature starts to rotate, the CEMF (counter electromotive force) is generated due to the interaction between the armature conductors and the magnetic field. This CEMF opposes the applied voltage and reduces the net voltage across the armature, which in turn reduces the line current. As the speed of the motor increases, the CEMF also increases and the line current decreases further.
