Polarity gain circuit

Using the electrode resistances (R anode and Rcath) gained from simulation with an equivalent circuit, the individual cathode and anode polarization curves can be determined, as shown schematically in Figure 3.16 [23],... 

Before polarization is discussed, it is imperative to understand how one measures polarization and to gain a qualitative understanding of how readily or not so readily polarizable a solid is. Consider two metal parallel plates of area A separated by a distance d in vacuum (Fig. 14.1a). Attaching these plates to the simple electric circuit, shown in Fig. 14.1a, and closing the circuit will result in a transient surge of current that rapidly decays to zero.
