Earth resistance is measured by using earth Resistance
meter. it is using for four probe method.Two electrodes
for potentials and the other two for currents. There are
two methods, viz. Schlumberger method and Wenner method in
which two types of electrode assembly. There are special
formulae to calculate the resistance from the apparent
resistivity we get from the instrument. There are special
software to interpret the data.for current.
