Voltage and electrode surface area

TL;DR Summary

relation between minimum voltage and surface area of electrode

Hi

I am looking to find the equation that determines the minimum (and if possible maximum that might damage the electrode) voltage that starts the electrolysis process for a given area of a graphite electrode in a brine solution medium (lets say 30%) at equilibrium state.

Also how does the relation of voltage and maximum possible current to be applied be determined ?

Any help is greatly appreciated.

Voltage is not electrode surface dependent. Current is.

For the Minimum Voltage, the Wikipedia article is pretty good. And as Borek says, the electrode areas affect the current, not this minimum voltage:

Electrolysis of water requires a minimum potential difference of 1.23 volts, though at that voltage external heat is required from the environment.
