Answer / anand yadav

Wrong perception. AC or DC , if there is a potential difference current between two points or objects (including earth) and there is a suitable path, current will flow.
Tell me, if DC is not flowing to Earth then how do we check earth resistance in every industry / every electrical installation.

if dc will flow to earth,there will be cause of fault.
