Theoretical analysis has been employed to study the effects of electrical conductivity and viscosity of a liquid on its electrodispersion from the edge of a capillary, through which the liquid is supplied to a discharge system. It has been shown that, when a high-conductivity and low-viscosity liquid is dispersed, it emits strongly charged small droplets, which are primordially unstable with respect to their own charges and disintegrate into several hundred still smaller droplets, which are also strongly charged and unstable. A corona discharge is ignited around each droplet and a glow arises, which is referred to as the "fan" glow. When a low-conductivity or a high-viscosity liquid is dispersed, it emits small charged droplets, which are stable with respect to their own charge (in the first case) or strongly charged droplets, which disintegrate into two or three droplets stable with respect to their own charge (in the second case).
