and Motors power mentioned in KW?.

Answer Posted / yogesh

Transformer and genrator PF depends on the nature of

factor

Therefore Transformer and genrator capacity shown in KVA (
Without PF ) and motor Capacity shows in Kw ( with power
factor )

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened.
