resistance. We can easily test the length dependence and simultaneously find the resistivity of a simple pencil lead. OBJECTIVES • Consider the difference between resistance and resistivity • Measure the dependence of resistance on the length of a graphite rod • Calculate the resistivity of graphite and compare it to the known value

Resistivity is a fundamental material property (like density or melting point), while the total resistance (R) depends on the material, the geometry, and the temperature. The dependence on geometry (really, a volume dependence: cross-sectional area (A) and length(L)) can be quantified: = ρ.
Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric
1 Ιαν 2003 · Abstract and Figures. Electrical resistivity is a key physical property of all materials. It is often necessary to accurately measure the resistivity of a given material. The electrical...
Electrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current.
