| Abstract | ||
| The aim of this work is to determine the electrical conductivity of glow discharge in dry air at low pressure (0.15- 5 torr), using the (I-V) characteristic curve. From the axial electric field strength (E) and discharge current density (J), we study also the effect of both (helium-neon) laser of power (0.5 and Imw) the ultra-violet radiation of energy (254 and 366nm) on the electric conductivity at glow discharge, the result shows that the electric conductivity decreases with increasing pressure increases. We find that the conductivity increases when both radiation's | ||
