what is the properties of resistivity
Answers
Answer:
The property of resistivity depend on the kinds of metal or wire
Answer:
Resistivity is the resistance per unit length and cross-sectional area. It is the property of the material that opposes the flow of charge or the flow of electric current.
Resitivity is a measure of the resistance to electrical conduction for a given size of material. Its opposite is electrial conductivity (=1/resistivity). Metals are good electrical conductors (high conductivity and low resistivity), while non-metals are mostly poor conductors (low conductivity and high resistivity).
The resistivity of a material is a fundamental property of that material. The bases of procedure in resistivity surveying is to measure the potential drop on the ground surface associated with a known current flow into the earth and then calculate the apparent resistivity.
