The electrical-supply on the earth’s surface are propagate from the positive electrode to the negative electrode. The electrons flow from the negative electrode to the positive electrode. In the conductor wire, an electric current tends to pass through the wire shell. The charge density decreases in proportion to the depth, the increase in frequency, and the material permeability. Based on these factors, practically, the conductor surface is often extended by making fibbers. If one of the trajectories on the earth gives an electric voltage, then the earth is not a perfect conductor, the earth as a large object with a surface is predicted to be relatively difficult to deliver an alternating electric current. Based on the previous statement, the granting of an electric current, and will more difficult to flow when the frequency is increased. The aim of this research is to find out the phenomena of earth resistance in the range of 20Hz-600Hz. It is expected that this data are useful for determining the frequency of effective exploration or also as a consideration when interpreting data. The study is conducted by giving an electric field to two electrodes with a measured current. Two electrodes are plugged into the ground for injecting current, and two others electrodes to pick up voltage which was reached. The measurements were made with an oscilloscope. The frequency was varied while recording the current that flow. The current flowed from the square wave current source that could be varied from 20Hz to 600Hz. From this experiment, it is found that the voltage decreases relatives along with the increase in the frequency.
