Current–voltage characteristics of ionic liquid–air glow discharges

I–V characteristics of air glow discharge, ionic liquid–contact air glow discharge and ionic liquid–air glow discharge are presented and photographs of the discharges are shown. It is found that the I–V characteristics of the air glow discharge always obey Ohm's law but I–V characteristics of the ionic liquid–contact air glow discharge and ionic liquid–air glow discharge obey Ohm's law only up to a particular voltage. A sudden burst of the electrolyte is observed for currents above a critical current.
