Carbon nanoparticles (CNP) were synthesized in arc plasma discharge using a simple, low-cost and toxic-free precursor gas. The structural and electrical characteristics were examined. The diameter and the height of the grown CNP was 28.5 μm and  316.7 μm , respectively. SEM image showed existence of a high density and uniform nanostructures within the cylindrical bulk CNP tube. The average diameter of the nanoparticles is 600 nm. The electrical characteristics revealed  low resistance with R = 7.23 mΩ with Cu electrodes.  In addition, the device exhibited a   high conductivity of 6.8 x 105 Scm-1. These results indicate the potential of CNP material for power device applications.
