Voltammetry in which the electric current is recorded as the electrode potential is varied linearly with time. See figure.
Notes: - The peak current is expressed by the Randles–Ševčík equation.
- The scan is usually started at a potential where no electrode reaction occurs.
- LSV corresponds to the first half cycle of cyclic voltammetry.
