Answer Posted / kuldeep

grounding is use to protect the instruments from flow of
large current while earthing is the old name of grounding
done by the peoples for both purposes 1_to save the
instruments from the large current 2_to increase the level
of voltage in case of low voltage by giving water to that
place where earthing is carried out

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. Why does the strand conductor of Electrical power transmission line make twist?
