Investigating Long-Term Electric Current Fluctuations in Electrolytic Cells and Tunnel Diodes

Abstract

The paper presents long-term measurement results concerning the Kullback --- Leibler divergence variations for electric current fluctuations in electrolytic cells and relative dispersion variations for electric current fluctuations in tunnel diodes. It is possible to transition from investigating current fluctuations in electrolytic cells to measuring similar fluctuations in tunnel diodes due to the charge carrier mass in diodes being considerably lower than masses of electrolyte ions. This decrease in mass leads to an increase in the sensitivity of the experimental installation. We found that the magnitude spectrum of Kullback --- Leibler divergence variations has a maximum corresponding to a period of 25.25 days (606 h). As for the magnitude spectrum of relative dispersion variations, its maximum is observed at the signal period of 25.88 days (621 h). These periods are close to the sidereal period of the Sun, that is, 25.38 days (609 h). We propose to use tunnel diodes with high peak current values and high direct forward voltage applied in order to increase the sensitivity of the experimental installation
