Due to the high viscosity of Arabic gum (AG) and its suspension characteristics, it is applicability is found in medical, lithographic, textiles, paints and cosmetics industries. However, its workability with respect to color has not been investigated. The advancement in technology and the drive to develop new frontiers in the fabrication of electronic components using environmentally friendly material has driven this research to understand the effect of color variation in the conductivity and resistivity of AG. Instrumentation method was used to determine the electrical conductivity and resistivity of the AG sample with respect to color variations. The result obtained shows that, AG (black) has the highest conductivity of 7.56 µS/m. whereas AG (white) has the lowest conductivity of 4.55 µS/m. However, the results for resistivity were vice versa. It is concluded that in the fabrication of communication devices, AG (Black) is more suitable for the fabrication of semiconductor materials due to its high conductivity and low resistivity value.
