Samples of cotton lint which had been kept in a controlled environment to stabilize their moisture content were placed in acrylic sample holders equipped with aluminum ends and compressed to a constant density, 0.3 grams/cm³. The electrical resistance of the samples was read with a megohm meter. The resistance varied with moisture content and ranged from 5000 megohms at 3% moisture content to 300 megohms at 10% moisture content with substantial uncontrolled variation (30% of the reading) at all moisture levels. The resistance of the samples was found to vary linearly with sample thickness but it did not vary in an inverse linear way with sample cross sectional area. An equation relating sample geometry, sample moisture content, and sample resistance was developed.
