WebbSimplified Randles Cell The Simplified Randles cell is one of most common cell models. It includes a solution resistance, a double layer capacitor and a charge transfer (or polarization resistance). The double-layer capacitance is in parallel with the charge-transfer resistance. In addition to being a useful model in its own right, the Simplified WebbThe Nyquist Plot for a simplified Randles cell is a semicircle. The solution resistance can be found by reading the real axis value at the high frequency intercept. The real axis value at the other (low frequency) intercept is the sum of the polarization resistance and the solution resistance.
