Artist's Description

This os photo I took at night, while traveling, a trial shoot of a beautiful bronze metal sculptured back lighted lamp, I just tough the lighted eyes and mouth would be cool to capture, funny it turned up showing a kind of electrical arc going down from the ceiling to the floor, showing on the photo and at the time of the capture I never saw this in my viewer , unusual and bizarre for the least! AS IS right out of the camera no manipulations what so ever
Camera: Compact Photosmart HP R927

Electrical Arc:
An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, resulting from a current flowing through normally non conductive media such as air. A synonym is arc discharge. The phenomenon was first described by Vasily V. Petrov, a Russian scientist who discovered it in 1802. An archaic term is voltaic arc as used in the phrase “voltaic arc lamp”.

Undesired arcing:
Undesired or unintended electric arcing can have detrimental effects on electric power transmission and distribution systems and electronic equipment. Devices which may cause arcing include switches, circuit breakers, relay contacts, fuses and poor cable terminations. When an inductive circuit is switched off the current cannot instantaneously jump to zero; a transient arc will be formed across the separating contacts. Switching devices susceptible to arcing are normally designed to contain and extinguish an arc, and snubber circuits can supply a path for transient currents, preventing arcing. If a circuit has enough current and voltage to sustain an arc formed outside of a switching device, the arc can cause damage to equipment such as melting of conductors, destruction of insulation, and fire. An arc flash describes an explosive electrical event that presents a hazard to people and equipment.
