In a theoretical analytical way, the peculiarities of the influence of the viscosity of a liquid on its electro-dispersion, from the end of the capillary, through which the liquid is supplied to the discharge system, or during the decay of a strongly charged drop, were investigated. It was shown that when a low-viscosity liquid was electrodispersed, it emited highly charged small droplets, initially unstable with respect to its own charge, breaking up into a couple of a hundred even smaller and highly charged ones, around which a corona discharge was ignited. As a result, a fan-shaped glow appeared at the top of the meniscus of the liquid at the end of the capillary or at the top of the decaying charged drop. For a viscous fluid, a series of successive decays of charged daughter droplets were immediately interrupted due to the damping effect of viscosity after a single split in half and the formation of self-charge-resistant droplets, and no corona discharge flare was formed.
