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.
