In linear-sweep voltammetry and related techniques, the empirical quantity defined by the equation \[\frac{i_{p}}{A\ \sqrt{\nu}\ c_{\text{B}}}\quad \left(=\frac{j_{p}}{\sqrt{\nu}\ c_{\text{B}}}\right)\] where \(i_{p}\) is the @P04457@, A is the area of the electrode-solution @I03082@, \(\nu\) is the rate of change of @A00424@, and \(c_{\text{B}}\) is the bulk concentration of the substance B whose reduction or @O04362@ is responsible for the peak in question.
