Answer 2

*The Voltage generated in the armature, placed in a rotating Magnetic Field, of a DC generator is alternating in nature.

*The commutation in DC machine or more specifically commutation in DC generator is the process in which generated alternating current in the armature winding of a dc machine is converted into direct current after going through the commutator and the stationary brushes.

* Again in DC Motor, the input DC is to be converted in alternating form in armature and that is also done through commutation.

*This transformation of current from the rotating armature of a DC machine to the stationary brushes needs to maintain continuously moving contact between the commutator segments and the brushes.
