Click to edit Master subtitle style 5/10/10 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 the current is measured as well, it is possible to determine an effective or apparent resistivity of the subsurface.

Click to edit Master subtitle style 5/10/10 Two of electrical resistivity surveying techniques are Profiling 1. In this case ,the spacing between the 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.
