The earth resistivity is measured in

Right Answer is:



The term “earth resistivity” expressed in ohm-centimeters (abbreviated ohm-cm) is one basic variable affecting resistance to earth of an electrode system.

Measurements of earth resistivity are also useful for finding the best location and depth for low resistance electrodes, as well. Such studies are made, for example, when a new electrical unit is being constructed, such as a generating station, substation, transmission tower, or telephone central office.
