I've read the next passage:
"This is an important concept in EIS, because it tells us something about the timescales on which different processes are occurring. This equation also allows you to calculate capacitances in these elements knowing only the resistance (from the diameter) and the relaxation frequency.".
My question is: what diameter they are talking about? and how to calculate the resistance knowing this diameter?
Ref: http://lacey.se/science/eis/simple-circuits/
There we refer to the diameter of the electrode, which is necessary to calculate the area of the electrode
Hi,
I think that they are refering to the diameter of the half circle... It directly gives you the resistance *r.
The cutoff frequency is on the top, allowing to have RC (2pi*f* = 1/RC)
hope it helps
Julien Bustillo how can I get the r* knowing the diameter of the half circle ?
