At a dropping electrode, the total current that flows at the instant when a time
has elapsed since the fall of the preceding drop. At any other electrode, the total
current that flows at the instant when a time
has elapsed since the beginning of an electrolysis. The instantaneous current is
usually time-dependent and may have the character of an
adsorption,
catalytic,
diffusion,
double-layer, or
kinetic current, and may include a
migration current. A plot of the dependence of instantaneous current on time is commonly called an
'
i-t curve'.
