electric arc
Gap-jumping current
An electric arc is a visible discharge of electricity across a gap between two conductors, producing intense light and heat.
The current ionizes the air, creating a continuous plasma bridge.
Electric arcs power arc welding, arc lamps, and plasma cutters, but also occur dangerously as unintended short circuits.
Lightning is a natural electric arc.
