Electrolyte Resistance from Surface of an Electrode to any Distance

These circuits are used for measuring the resistance of solutions or gases to measure an ohmic IR drop through a material or solution.

𝑅 − Resistance to electrolyte(ohms)
𝜌 − Electrolyte resistivity(ohm⁄cm)
𝐿 − Distance through the electrolyte traveled by current,assumed 1cm.
𝑑 − Distance from the central electrode(cm)
𝐾_𝑎 − Geometry factor for the central electrode
𝑟 = 𝐾_𝑎𝜌

Some commonly used electrode arrays and their geometric factors. Note that for the multiple gradient array, the total array length is ‘(s + 2) a’ and the distance between the center of the potential dipole pair P1 – P2 and the center of the current pair C1 – C2 is given by ‘ma’.
