Electric resistivity is defined as the electrical resistance offered per unit length and unit cross-sectional area at a specific temperature and is denoted by ρ. Electrical resistance is also known as specific electrical resistance. The SI unit of electrical resistivity is ohms.metre. Following is the formula of electrical resistivity:

Dec 03, 2017·I'm getting ready for some upcoming exams and I find myself tripping up over resistivity equations. I've been working through example questions, but this one confuses me. Example: Find the CSA of a single copper cable 500 metres long, which carries a current of 2.5A, and has voltage drop of 3.58V, resistivity of copper being 1.72x10(-8) ohm/m.

Jul 01, 2013·This study demonstrates that the electrical resistance of standard nitrile gloves, a common glove type used for clinical procedures, reduces when worn and reduces still further when used to perform chest compressions. Additionally, some gloves may have macroscopic tears even when new, rendering them completely permeable to electrical current.

The electrical resistivity method has some inherent limitations that affect the resolution and accuracy that may be expected from it. Like all methods using measurements of a potential field, the value of a measurement obtained at any location represents a weighted average of the effects produced over a large volume of material, with the nearby ...

Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current.A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ ().
