Answer Posted / sukesh
as we know that rating of any machine is decided by its temp
rise.temp rise due to the presence of losses in the t/f.
2 losses are there .one is iron loss and other one copper loss.
\iron loss depends on voltage.(v.i).
cu-loss depends on current.(i2.r).
so rating of t/f as well as generator both is in kva.
and for dc motor see the reply of HEMRAJ.
