As per BIS, Earth pit resistence value?..

Answer / ramdarkmaster

Earth's resistance will differ from place to place....
it all depend's on soil resistivity... some places it may be red soil, were as in some places it may black cotton soil..
so we need to measure the resistance using earth tester..
but normally it will in few ohms.
