Chapter 15- From Macroelectrodes to Microelectrodes: Theory and Properties

Voltammetry involves the application of a potential that varies with time and the measurement of a current that flows between a working and a reference electrode. Voltammetry can therefore be defined as the exploration of the three-dimensional space that relates to potential, current, and time.1 However, under suitable circumstances, simplified conditions can lead to a unique relation, not involving time, between current and potential; such situation provides the so-called steady-state voltammetry.2
