Gold Capacitors Technical Guide
Principles and Operation of Gold Capacitors
2-3 Equivalent Circuit
The equivalent circuit used for conventional capacitors can also be applied to Gold Capacitors.
In an electric double layer capacitor, the electric double layer is formed on the surface of the activated carbon that is
in contact with the liquid electrolyte. As shown in Fig.5.
Because the activated carbon particles are used as electrodes, each carbon layer (Fig.5) functions as an electric
double layer capacitor having the capacitance value of C
n
.
In order for the capacitance C
n
to charge, two resistances are needed as described in
Fig.6.
The resistance R

moves ions while resistance Rs is the charging resistance. The
double layers formed on the activated carbon surfaces can be shown as parallel
circuits.
