Resistivity
</dt>
In electricity, a characteristic proportionality factor equal to the resistance
of a centimeter cube of a substance to the passage of an electric current
perpendicular to two parallel faces. Also called specific resistance. ''R
= ρ( l/A ) where R is the resistance of a uniform conductor,
l is the length, A is its cross-sectional area, and ρ is
its resistivity. [[/a>|/a>
