Abstract
This article aims to present methods for measuring the electrical properties of sample - a granular material - rapeseed seeds developed in physics research laboratory at the Slovak University of Agriculture in Nitra Electrical properties were measured with LCR meter. Resistance R, impedance Z, capacity C, relative permittivity of six samples of rapeseed seeds with different moisture content were measured. The results are represented graphically and analytically. Obtained results are analyzed. The measured values and results obtained allow to conclude that resistance, impedance and capacity of rapeseed seeds functionally dependent on the frequency, as obtained by other authors. Research on electrical properties of biological materials and the results can be used when constructing the apparatus for measuring moisture content based on electrical and dielectric properties of materials. Knowing the dependencies would allow to find the most optimal and accurate method for measuring moisture content in agricultural production.
