Resistivity of fresh water
WebThe Electrical conductivity is the inverse of the resistivity and is given by. σ = 1/ρ. Where, σ = electrical conductivity. ρ = resistivity. This ability of conductance in water is directly proportional to the concentration of the … WebThe vertical electrical resistivity sounding methods (VES) are depth sounding galvanic methods. The electrical resistivity of rock is a property which depends on lithology and fluid content. The resistivity of coarse-grained, well-consolidated sandstone saturated with fresh water is higher than that of unconsolidated silt of
