conductivity
Pronunciation: /kɒndʌkˈtɪvɪti/
noun ( plural conductivities)
- (also electrical conductivity) the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field which causes the flow of current.
- (also thermal conductivity) the rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance: they constructed models from two materials with different thermal conductivities
