Earth resistivity refers to the ability of soil and rock to resist the flow of electric current. This property is influenced by factors such as moisture content, temperature, and mineral composition. Lower resistivity indicates better conductivity, making it easier for electricity to pass through the ground. Understanding earth resistivity is crucial for various applications, including geotechnical engineering, grounding systems, and environmental studies. Engineers and scientists measure resistivity to assess soil conditions, design effective grounding systems for electrical installations, and evaluate the potential for geothermal energy extraction.
