Abstract

The electrical behaviour of some of the vegetables, fruits and food grains have been studied using the method of two probe resistance measurement at various levels of frequencies. The aim of the present study was to investigate the behaviour of its capacitance as a function of frequency. Electrical capacitance was found to decrease exponentially with increasing frequency, but the dielectric constant was a function of the moisture content there by increasing its ability to store energy.
