Mass-specific electrical resistance

from Wikipedia, the free encyclopedia

The mass- specific electrical resistance of a substance is the ratio of the specific electrical resistance to the specific density . The SI unit is Ω · kg / m². The reciprocal value is the mass-specific electrical conductivity (unit: S · m² / kg).

Materials with a low mass-specific electrical resistance are suitable for building systems in which, in addition to electrical conductivity, a low mass is also important. Despite high conductivity, it may be useful, rather than copper or silver rather aluminum to be used.
