A) A schematic of a three-electrode system used in modern electrochemical potentiometry B) a plot of voltage at the working electrode (relative to the reference electrode) change over time during cyclic voltammetry C) A prototypical voltammogram, the current through the sample is measured at the voltage changes over time (as seen in B).
