  • resistivity data can be collected using different techniques.
  • Fluid- resistivity logs record the electrical resistivity of water in the borehole.
  • resistivity traverses are used to map lateral variations in resistivity and are not usually used to provide bedrock depths.
British Dictionary definitions for resistivity


the electrical property of a material that determines the resistance of a piece of given dimensions. It is equal to RA/l, where R is the resistance, A the cross-sectional area, and l the length, and is the reciprocal of conductivity. It is measured in ohms ρ Former name specific resistance
the power or capacity to resist; resistance

resistivity in Science
A measure of the potential electrical resistance of a conductive material. It is determined experimentally using the equation ρ = RA/l, where R is the measured resistance of some length of the material, A is its cross-sectional area (which must be uniform), and l is its length. It is measured in ohm-meters.
