Dictionary:Polarization resistance

The factor ${\frac {RT}{nFJ_{0}}}$ employed in overvoltage theory, relating overvoltage $\eta$ to current density J:

$\eta =-{\frac {RT}{nFJ_{0}}}J$

R is the gas constant, T the absolute temperature, n the number of molar equivalents, F the Faraday, and J_o the exchange current density, all in cgs units. The units of polarization resistance are ohm-cm².
