The theory of a reversible wave for linear sweep voltammetry at a microring electrode is described. The behavior of the current vs. potential curve is discussed. The max. current is expressed by an approx. equation. To verify the theory, experiments were carried out on Au and Pt microring electrodes with K4Fe(CN)6 in 0.5 mol/dm3 KCl solution The experimental results agree well with the theor. ones.
