1stly I would like to ask,what is meant by brushed
alternator??I mean what are the physical aspects of this
machine? i.e how the brushes are connected is the rotor??

we all know that DC generator's output is DC component.
and brushed alternator-by name it self we can say that its
output is alternating component.so we can conclude that
brushed alternator is the alternating component taken from
brushes.then how can u call it as a DC generator.???!!!!
