This equation defines the relation between the concentrations of an ion on either side of a membrane that it perfectly selective for that ion and the potential difference (voltage) that will be measured across that membrane under equilibrium conditions.

This equation can be used to calculate what the output might be from a particular transformer, or to work out how to design a transformer to make a particular potential difference change ...
