Abstract
Discussed are one-dimensional and two-dimensional cases of potential distribution in electrode. It is demonstrated that if the rate of current formation in each point of electrode was (according to Faraday's law-) proportional to transferred electrical charge as well as to deviation of potential from equilibrium potential, then the problem of potential determination brings to equation solution in the form: Δφ = k2φ , where Δ – Laplace operator; φ – potential deviation from equilibrium; k – a constant dependent on electrode parameters.
The analysis of solutions obtained demonstrates that the design features of current leads produce unconformity of current and potential distribution in electrodes. As a result, the current-formatting processes over the electrode area occur with different rate The rate of charge/discharge processes in sections adjacent to current leads is higher than in remote sections and periphery of electrode. Calculation indicates that the increase of potential nonconformity in electrodes results in increase of inner resistive component.
Corona discharge characterization is essential for industrial plasma devices such as electrostatic precipitators, where effective sharp electrode configurations can generate high discharge currents at relatively low potential differences efficiently and measurably. This study aims to determine the characteristic equati...

To investigate the influence of electrode surface roughness on gas discharge characteristics under micro-gap conditions, direct-current breakdown experiments were carried out in atmospheric air using a nano-positioning system. Breakdown tests were conducted for five metal electrodes over the electrode gap distances fro...

Non-thermal plasma shows great potential for air purification because of its low temperature, abundant reactive species, and moderate power density. However, in atmospheric-pressure air, the short electron mean free path readily promotes filamentary discharge, leading to the localized distribution of discharge energy a...
