when an alternating potential is applied across two conductors whose spacing is large as compared to their dimaters, there is no appparent charger i n the condition of atmosphereic air surroundingthe wire if the applied voltage is low.
However , when the appiled voltage exceeds a certain value,called "critical disruptive voltage", the conductors are surrounded by a faint violet glow called "Corona".
