  • resistivity

    the specific quantitative measure of a material's opposition to electrical flow

文法句型

conductivity + of + substance

adjective + conductivity

conductivity + measurement/level/test

用法筆記

Conductivity is a technical term used mainly in physics and engineering. It is almost always paired with electrical or thermal to specify the type of conduction being described. Use high/low (not good/bad) to describe the degree.

常見錯誤

Copper has a good conductivity.
Copper has high conductivity.
conductivity is described as high or low, not good or bad.
The conductivity of this wire is very conduct.
This wire has very high conductivity.
conductivity is a noun; use an adjective (conductive) for the property description.
