The non- where = = area of the electrode-solution = time. Capital letters should be used as subscripts to avoid the possibility of confusing this symbol with that for the
faradaic current
associated with the charging of the electrical double layer
at an electrode-solution interface
, given by: surface charge density
of the double layer, interface
and limiting diffusion current
.
