electrical arcing
Current leaps gaps
Electrical arcing is the visible discharge of electricity across a gap between two conductors, producing intense light and heat.
It occurs when voltage is high enough to ionize the air or other medium, creating a conductive path: The faulty wiring caused electrical arcing in the wall.
Arc welding harnesses this phenomenon deliberately, while unintended arcing in electrical systems poses fire and shock hazards.
