Glow Discharge

Glow Discharge, in Electricity, means the dissipation of a enlarge of electricity of high potential by convection. Particles of air are charged by contact, and are then repelled. Faint sparking is produced at each small transfer and a glow is visible around the surface of discharge. The convection is more vigorous where the surface has greatest curvature, and there the glow is more intense. [Brush Discharge.]
