If difficulty is experienced with the accurate location of a peak potential, the potential measured at half the peak height (E p/2 ) can be used to calculate it, lying (56.5/n) mV more positive than the E p (for a reduction).

Among the experimental variables under our control are the initial potential, the final potential, the scan rate, and whether we choose to stir the solution or leave it unstirred. We call this linear sweep voltammetry.

This is commonly done with an instrument called a potentiostat, which for these measurements is capable of applying variable potentials to the working electrode relative to a reference electrode while measuring the current that flows as a result of the electrode reaction.
