Question

Function
1.Armature
I have written that it is used to move fast
2.Split Ring
I have written that it is used to connect the circuit
3.Brush
I have written that it helps to move the coil efficiently.
Are all these correct ?

Answer 1

Armature is used for increasing magnetic energy and speed of coil.

Split ring reverses the direction of current in a DC circuit

Brushes make sure to act as a protective coating as well as for making the split rings stay at a place.

Hope this helps
Cheers

All the best for Math tomorrow
