Soil electrical conductivity
WebThe electrical conductivity of an aqueous solution is its ability to conduct an electrical current. The electrical conductivity is an important parameter used to estimate the level … Soil resistivity is a measure of how much the soil resists or conducts electric current. It is a critical factor in design of systems that rely on passing current through the Earth's surface. It is a very important parameter for finding the best location of a transmitter working on low frequiencies (VLF, LF, MF and lower shortwave) as such radio stations usually use ground as counterpole. An understanding of the soil resistivity and how it varies with depth in the soil is necessary to desig…
