Abstract

Electrical properties determination is used in a variety of disciplines and industries. This paper provides a quick overview about the use of electrical properties in agricultural materials like rice bran. Electrical properties like electrical resistance, capacitance and electrical conductivity of rice bran subjected to different moisture contents (9.4, 12, 15, 20, 25, 30 & 35% w.b.) for ohmic heating were determined through LCRQ meter. Experimental data was analyzed by one way ANOVA through MS-Excel. Results showed that capacitance and electrical conductivity were significantly (P<0.05) increased with increase in moisture contents (i.e., from 9.4 to 35%) where as the resistance significantly (P<0.05) decreased with increased moisture contents. Correlation equations for resistance, capacitance and electrical conductivity against moisture content with R2 values of 0.983, 0.99 & 0.983 respectively were developed. The mean±standard deviation for capacitance and resistance were observed a
