What is electrical conductivity?

Electrical 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.

Each material is capable of carrying current. The capacity and quantity of that current is what we call electrical conductivity.

This type of property is called intrinsic property and will depend on the atomic and molecular structure of the material.

A good example of a material with electrical conductivity is metal.
