I am confused on how to measure the resistance of the electrolyte in an electrolytic cell. Any tips would be appreciated. Thanks.

What have you found so far, and what of what you found is confusing?

The relation between voltage and current is generally not proportional, so there is no "resistance", or this would require some definition and depend on what you're interested in.

For instance, you might be interested in the differential resistance, or the voltage variation divided by some current variation, around an operating point where electroplating occurs. Then measurements are possible that give values usable if not reproducible.
