WebA new resistivity sounding technique is proposed using three electrodes (pole-dipole) in which current and potential electrodes can be arranged depending upon the availability of open space. In this technique only one current electrode is moved along a line towards one side making an angle with the dipole axis.

WebMar 14, 2024 · If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm –3 and that of the soil as 1.20 g cm –3. Even though sand is made of rock fragments, its density is less because the porosity of sand lowers its bulk density (as shown below).
WebType of Soil Affects Resistivity Whether a soil is largely clay or very sandy, for example, can change the earth resistivity a great deal. It isn’t easy to define exactly a given soil; “clay” can cover a wide variety of soils. Therefore, we cannot say that any given soil has a resistivity of so many ohm-cm.
