are enclosed in parentheses: (R1C1) means R1 is in parallel with C1. Example Matrix:
or higher, the model is likely incorrect or your initial parameters were too far off.
Used in place of a capacitor to model real-world, non-ideal double layers with surface roughness or porosity. It introduces a distortion factor ( ) between 0 and 1.

Before jumping into the "how-to," it’s essential to understand what makes ZSimpWin a go-to software in the world of EIS.
To give you context, here is how ZSimpWin compares to its main rival, :
Represents ohmic resistances, such as electrolyte resistance ( Rscap R sub s ) or charge transfer resistance ( Rctcap R sub c t end-sub are enclosed in parentheses: (R1C1) means R1 is
