Hello, I am trying to model a three electrode set-up but I am struggling in how to define the applied potentials at my WE, RE, and CE.

I will be running both EIS and CV with my design, and I would like to understand the physics in context to my results. I struggle with defining the electrode potentials with respect to each other based on what the potentiostat applies during measurements.

Currently, I am applying a 10 mV potential across the WE and RE (5 mV @ WE and -5 mV @ RE) and grounding the CE. However, when I plot the current density, it seems that I am seeing large currents between my WE and RE. I know this should not be the case because the potentiostat inputs a high impedance at the RE so that very little current will pass. Any advice would be extremely helpful.
