Resistivity method

An apparent electrical resistivity is derived by measuring an electrical current flow between two electrodes and the difference of the electric potential between two different electrodes. By analysing different measurements a model of the electric resistivity can be derived due to the different sensitivity distributions of the measurement configurations.

Typical configurations are (mainly)

  • Schlumberger configuration
    used for depth sounding
  • Wenner configuration
    used for depth sounding, mapping and 2D profiles
  • Dipole-Dipole configuration
    used for 2D profiles

Typical depth penetraton is normally the upper 10 m.

The resistivity method is used at archeological sites and for engineering targets.
