resistivity
Americannoun
-
the power or property of resistance.
-
Also called specific resistance. Electricity. the resistance between opposite faces of a one-centimeter cube of a given material; ratio of electric intensity to cross-sectional area; reciprocal of conductivity.
noun
-
Former name: specific resistance. ρ. the electrical property of a material that determines the resistance of a piece of given dimensions. It is equal to RA/l , where R is the resistance, A the cross-sectional area, and l the length, and is the reciprocal of conductivity. It is measured in ohms
