Exploring of factors influencing the rocks resistivity value: comparative study of resistivity values in some areas

Abstract

Geophysics has been the success to solve environmental issues, engineering, and hydrogeology. One of the geophysical methods is electrical resistivity that has been used to survey near of surface. Electrical resistivity is a geophysical method that has a working principle by injecting DC (Direct Current) that has high voltage into the ground. The result can be used to obtain resistivity value that is passed by electrical current based on Ohm's Law. Factors that influence the rock resistivity value are included porosity, water content, and type of soil. The purposes of this study are to compare the rock resistivity values in some areas and to know the factors that influence the rock resistivity values in those areas. The method used in this study is to compare papers about some case studies using the electrical resistivity method.
