La différence entre le courant qui est effectivement obtenu, à toute valeur donnée du potentiel de l'électrode indicatrice ou de travail, pour la réduction ou l'oxydation d'une substance électroactive ionique et le courant qui serait obtenu au même potentiel s'il n'y avait aucun transport de cette substance dû au champ électrique entre les électrodes. 1, record 14, French, - courant%20de%20migration

Par convention de signe, le courant de migration est négatif pour la réduction d'un cation ou l'oxydation d'un anion et il est positif pour l'oxydation d'un cation ou pour la réduction d'un anion. Le courant de migration a donc tendance à augmenter ou à diminuer le courant total observé. Dans tous les cas, le courant de migration tend vers zéro lorsque le nombre de transport de la substance électroactive diminue par augmentation de la concentration de l'électrolyte support et donc la conductivité. 1, record 14, French, - courant%20de%20migration
