Answer / raghavendran.r

The Above stated answer is true but I would like to add
more to that.there is a technique called as Werner
Configuration Technique where we have in total 4
electrodes.The first and fourth electrode is connected to
Current source and 2nd and 3rd electrode is connected to
voltage source and all 4 are inserted into the earth.And
the data is recorded by a Earth resistivity meter.
