Analysis on the fundamental properties of electric resistance of wood III

Abstract

To see the effect of temperature upon the specific resistance of wood, the temperature of wood and its corresponding specific resistance were measured from-10° to 45°C. Four coniferous woods (Hinoki, Matsu, Tsuga and Sugi) were used as samples.
From the results, the equation between sp. resistance R, and absolute temperature T would be R₈=Ae^B/T, where A and B are the functions referring to the moisture content. This formula so resembled the general one of viscosity of liquid, that these properties of electric resistance of wood were studied as ionic conduction in relation to the viscosity of water.
