In a simple DC motor, the Armature reverses the current every half revolution of the loop.
Answer : Option C
Explanation:
DC motor works on the principle of electromagnetic induction that when a current carrying conductor placed in a magnetic field is said to exert a mechanical force.
It converts electrical energy into mechanical energy. In dc motor, the armature rotates in clockwise or anti clockwise direction. When the armature rotates the current reverses its direction for every half rotation which then passes on to the commutators, brushes and slip rings.
