Direct-Current Resistivity Survey

Direct-current (DC) resistivity is an active source electrical technique in which current is applied to the ground using electrodes and the earth response (voltage or potential difference) is recorded. This survey generates a geoelectric section of apparent resistivity and enables an inference of subsurface geology.[1]
