In this paper the results obtained by experimenting in the frequency-domain
on a number of pyrite crystals are given. These crystals are connected in series
by ionic, linear elements in order to obtain a physical circuit as clear as
possible with regard to the membrane polarization. The data provided by these
experiments of tolerably not-poisoned, electrode polarization are obtained
with 0.1 – 1000 Hz interval. Both resistance and capacitance of the equivalent
impedance in the mean surface impedance shown by the crystals are plotted versus
frequency.
The effect connecting in parallel to this circuit an ionic, linear system is
also considered.
