WebIn the three-electrode set-up, the working electrode usually is the ground. But in a bipotentiostat, the two working electrodes, say ring and disk, are controlled separately. In that case, I think ... WebAs a potentiostat uses digital signals to determine the potential to output, any change in potential will appear as a step, and a scan profile a series of steps over time, as shown in figure 4. The applied potential resolution determines how small these steps can be, as it is the smallest change in potential that can be output by a potentiostat.
