Soil resistivity is a measure of how strongly soil resists the flow of electric current. It is influenced by factors such as moisture content, temperature, and the type of minerals present in the soil. Lower resistivity values indicate that the soil conducts electricity well, while higher values suggest poor conductivity. Understanding soil resistivity is important for various applications, including electrical grounding, geotechnical engineering, and environmental studies. Accurate measurements help engineers design safe electrical systems and assess the suitability of soil for construction projects.
