Etymology

Origin of conductivity

First recorded in 1830–40; conductive + -ity

Explanation

A material's conductivity is the extent that it allows an electric current to flow through it. Metal generally has high conductivity. In physics, the noun conductivity is used for the rate or degree that electricity, heat, or sound travels through something. So materials with high conductivity allow heat to flow quickly and completely through them. These substances are also known as conductors. Both words are rooted in the Latin conducere, "to lead or bring together."
