Resistivity survey

A resistivity survey is a method used to measure how much a material resists the flow of electric current. In geophysics, it involves passing small electrical currents into the ground through electrodes and measuring the resulting voltage differences. This data helps identify different underground features, such as rock types, water tables, or cavities, based on how the ground's resistivity varies. The survey provides valuable information for construction, archaeology, and environmental studies without the need for excavation, offering a non-invasive way to understand subsurface conditions accurately.
