Multidimensional signal processing | Inverse problems
Electrical resistivity tomography (ERT) or electrical resistivity imaging (ERI) is a geophysical technique for imaging sub-surface structures from electrical resistivity measurements made at the surface, or by electrodes in one or more boreholes. If the electrodes are suspended in the boreholes, deeper sections can be investigated. It is closely related to the medical imaging technique electrical impedance tomography (EIT), and mathematically is the same inverse problem. In contrast to medical EIT, however, ERT is essentially a direct current method. A related geophysical method, induced polarization (or spectral induced polarization), measures the transient response and aims to determine the subsurface chargeability properties. Electrical resistivity measurements can be used for identification and quantification of depth of groundwater, detection of clays, and measurement of groundwater conductivity. (Wikipedia).
Resistance & Resistivity, Example Problems
Includes four different worked examples for calculating resistance and resistivity. Resistivity is a property of a material that tells you how strongly it resists or conducts the flow of electric current. A low resistivity indicates a material that allows the flow of electric current. Res

Electrical conductivity in materials and resistivity vs resistance
Electrical conductivity is the constant of proportionality for electrical transport in response to the driving force of an electric field. It's completely analogous to mass and thermal transport (diffusion coefficient and thermal conductivity) in this way. We must also differentiate betwee
