A phenomenon where a flash over of electrical current leaves its intended path and travels through the air from one conductor to another is the definition of

Explanation:
Arc flash is the phenomenon where electrical current jumps through the air between conductors, creating a discharge that travels along an unintended path. This happens when the insulating clearance is exceeded or the air becomes ionized, forming a conductive plasma channel that lets current flow through the air instead of staying on the designed conductor path. The definition given matches this exact situation: current leaves its intended path and travels through the air from one conductor to another. In contrast, a ground fault involves current finding a path to the earth, a short circuit is a low-impedance connection between conductors (or to ground) that causes a large surge, and electrical noise refers to unwanted electromagnetic interference. The arc flash description uniquely captures current traveling through air between conductors.
