Relationship Between Resistance and Resistivity

In practice electrolyte resistivity is used in corrosion related circuits and electrical resistance is in electrical circuits.

PTLB Corrosion 2.4 Intro Image.png

𝑅 − Electrical resistance(ohms)
𝜌 − Electrolyte resistivity(ohm⁄cm)
∆𝐿 − Distance through the electrolyte traveled by current,cm.
𝐴 − Cross sectional area through which current flows(cm²)
