The chemical, thermodynamic relationship which permits calculation of the Reduction Potential of a reaction.

Nernst Potential

Otherwise known as reversal potential

$E=(RT/zF)ln(outside/inside)$

where R is the ideal gas constant, T is temperature in Kelvin, F is the Faraday’s constant, and z is charge of ion

Note that the Nernst potential is only applicable when the membrane is only permeable to one ion. So, in reality it’s not very useful at all.
