what is the difference between conductivity and resistivity
Resistivity and conductivity are reciprocals: Ï = 1 / Ï {\displaystyle \rho =1/\sigma } . Resistivity is a measure of the material's ability to oppose electric current. This formula is not exact, as it assumes the current density is totally uniform in the conductor, which is not always true in practical situations.
Popular Answers. 1  Yes, there is a relation between the pH and the electrical current flow [the conductivity] of a solution, but there are other factors that affect the conductivity. This topic, the conductivity of solutions, takes up a full chapter in a textbook on physical chemistry with many graphs and numerical tables.
