In a neon gas discharge tube Ne+ ions moving through a cross-section of the tube each second to the right is 2.9×1018, while 1.2×1018 electrons move towards left in the same time; the electronic charge being 1.6×10−19C, the net electric current is

As the electrons carry a negative charge the resultant current,I=2.9×1018+1.2×1018×1.6×10−19 towards right
