rinciple Principle Resistivity methods employ an artificial source of current , which is introduced into the ground through electrodes. The procedure involves measurements of potential difference at another electrodes in the vicinity of current flow. Because e current is measured as well it is possible to the current is measured as well, it is possible to determine an effective or apparent resistivity of the subsurface.

Two of electrical resistivity surveying chniques are techniques are Profiling 1. In this case ,the spacing between the ectrodes remains fixed but the entire electrodes remains fixed, but the entire array is moved along a straight line. 2. It detect the lateral change in the subsurface resistivity, not the vertical changes . 3. Interpretation of data from profiling surveys is mainly qualitative.
