Introduction Electrochemical experiments range from simple potentiostatic (chronoamperometry), to cyclic voltammetry (potentiodynamic), to complex AC techniques such as impedance spectroscopy. Moreover, each individual technique may have multiple possible experimental setups, often with a best option. This note discusses one aspect of these setups: the number of electrodes (or probes) used. Potentiostat as a Four-Probe Instrument … Read more
