Aah, that is exactly where I am having the issue. What happens during
the voltage step. Now I appreciate at the point of the step, dV/dt =
infinity (or close enough), so Icap is infinity, and the capcitor
fills instantly. However, because of the series resistance of the
electrode, peak delta I = delta V * Rs. But this is where I fall over.
Because what happens during Non-step voltages (ramps etc).
I also get that in a parallel RC circuit
Itot = V/Rm + C * dV/dt
But that leaves me in the same position, with dV/dt = infinity. So it
needs some kind of modifier, but I can't figure it out.
