Electrical Resistance and Resistivity. July 1, 2003. Evaluation Engineering. Interpreting a data sheet for a static-control product requires a certain level of knowledge and experience.

Conductivity and resistivity are widely used parameters for water purity analysis, monitoring of reverse osmosis, cleaning procedures, control of chemical processes and in industrial wastewater.

In the presence of a magnetic field, negative resistivity can produce a positive resistance, along with a sign reversal in the Hall effect, in GaAs/AlGaAs semiconductor devices.

Consequently, resistivity varies throughout a line, and resistance extraction needs to account for these secondary phenomena for improved resistance accuracy. Metal resistivity at different geometries ...
