Answer / k.prakashchandra

The resistance is infinity if the TR secondary neutral is
not earthed and it is zero if you use the same earth
conductor for Tr neutral earthing also. Further if you have
separate earthings for TR neutral and the earth conductor
,the resistance measured would be the sum of their ER
values, ignoring resistance of the conductors

how can we calculate the current
