partial anodic (cathodic) current

When a single electrochemical reaction occurs at an electrode (i.e. all other electrochemical reactions may be neglected):

$I = I a + I c$

where $I$ is the total current, $I a$ is the positive partial anodic current and $I c$ is the negative partial cathodic current. When more than one reaction is significant the reactions may be numbered and the numbers used as subscripts: $I 1,a$ , $I 1,c$ , $I 2,a$ , etc. Then:

$I = ∑ I i , a + ∑ I i , c$
