Question

why do we use slip rings on making of simple electric motor​

Answer 1

Answer:

slip rings provide a continuous transfer of power, signals, or data. Specifically, in AC motors, they transfer resistance to the rotor windings. Commutators, on the other hand, are used in DC motors to reverse the polarity of current in the armature

Answer 2

Answer:

to change the direction of the current

Explanation:

to develop opposite charges on both the ends so that the coil continues to rotate
