In various applications, heat energy is derived from electromagnetic energy, especially in microwave appliances. The heat is generated by electromagnetic induction hence understanding the properties of the material used in this application are much required. Also increase in biological awareness shifts the researchers toward the biodegradable material. The objective of this research is to investigate the dielectric and conductance of Polyvinyl alcohol-based nano-bagasse biochar. The network analyzer with a probe is used for the analysis of the dielectric property. The impedance analyzer is used to measure the conductance of the biochar. According to the results of the experiment, Biochar exhibits outstanding conductivity at 10 wt% and 15 wt% concentrations, with 1.46* 10-2 S and 3.87 *10-2 S, respectively. The dielectric loss is decreased at BIA 1200, implying that the nanocomposite at BIA 1200 has superior dielectric performance with less loss. The tangential loss factor and dielectric loss are both low for the BIA1200 combination. These high dielectric loss and constant improved composites could be used in many engineering applications such as defence, aerospace and automobile applications.
