The resistance and resistivity of clay has been investigated at Wilberforce Island Bayelsa State, Nigeria. This research focused on investigating the resistivity of clay using ground tester model 6470-B. Objectively, this will be achieved by testing the resistivity of clay at different depths and investigating it resistivities. Furthermore, the resistivity of clay depends on ground water salinity, humidity and temperature. Therefore, clay resistivity values varies depending on the type of terrain. Moreover, series of resistivity can be computed from resistance data at various depths interval and same plotted against depths. Hence, this research imbibed the four point Wenner method which uses four electrodes spaced at equidistances across the surface of the ground in a straight line, which defines the testing depth into the soil (clay). Nevertheless, resistivity tests on clay wereinvestigated in four different locations in Niger Delta University Wilberforce Island, Bayelsa State, Nigeria. The data collected from the tests were analysed and represented graphically using Microsoft Excel 2013. The results obtained from the experiment shows that increase in the distance between the electrodes leads to decrease in the resistivity values which determines the level of corrosiveness in the soil (clay). At a depth of 0.25m, the resisivity value was 50.8 &
