How do you measure IV curve using potentiostat? - Answers

To measure an IV curve using a potentiostat, you first connect the sample (typically an electrochemical cell) to the potentiostat's electrodes: the working, reference, and counter electrodes. The potentiostat is then programmed to sweep the voltage across the working electrode while measuring the resulting current. This data is collected at various voltage points and plotted to create the IV curve, which illustrates the relationship between current and voltage for the sample. Finally, the parameters can be analyzed to understand the electrochemical characteristics of the material.
