Abstract: The theory of the triangular-wave current excitation oscillographic chronopotentiometry has been derived by the use of Fourier transformation technique and response function additivity principle. The effect of current amplitude i₀, frequency f and depolarizer's Cto E-t curve were discussed. The modified E-t equation was also obtained when the effect of double electrode layer differential capacity be considered.

Key words: Triangular-wave current excitation, Oscillographic chronopotentiometry, Double electrode layer differential capacity
