Dr Richard Ogilvy, British Geological Survey (BGS), on the non-invasive characterisation of landfills by Electrical Resistivity Tomography (ERT). Electrical Resistivity Tomography (ERT) is a new and ...
Electrical resistivity is a basic property that quantifies a material’s opposition to current flow—it’s the reciprocal of conductivity. The resistivity of a material depends upon several factors, ...
When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...
