We call the resulting plot of current versus applied potential a voltammogram, and it is the electrochemical equivalent of a spectrum in spectroscopy, providing quantitative and qualitative information about the species involved in the oxidation or reduction reaction.

Potentiometry involves measuring potential without significant current and using the Nernst equation to calculate analyte activity. Coulometry is based on Faraday???s law to determine analyte quantity through electrical charge or current.

In polarography, as in linear sweep voltammetry, we vary the potential and measure the current. The change in potential can be in the form of a linear ramp, as was the case for linear sweep voltammetry, or it can involve a series of pulses.
