To form a voltaic arc, as an electrical current in a broken or disconnected circuit.
Islands or mountains arranged in a great curve. As applied to electricity, the luminous bridge formed by the passage of a current across a gap between two conductors or terminals.
Discharge of electricity through a gas such as lightning discharging through the atmosphere.
Annual Review of Electric Utilities Iowa Code § 476.6(16) directs the Utilities Board to conduct a periodic proceeding to evaluate the reasonableness and prudence of each rate-regulated public utility's procurement and contracting practices relating to the acquisition of fuel for use in generating electricity.
The effect generated when electrical current bridges the air gap between two conductors that are not touching.
An electric arc is a bright, hot (6000ºF) arc created by the electric current flowing across the gap between the tip of the electrode and the work. The arc melts the base metal and actually digs into it, much as the water through a nozzle on a garden hose digs into the earth.
electrical conduction through a gas in an applied electric field
A general term for a high intensity electrical discharge occurring between two electrodes in a gaseous medium, usually accompanied by the generation of heat and the emission of light
luminous discharge of electricity (light) between two electrodes.
Arc: A luminous discharge of electrical current crossing the gap between two electrodes
A low-voltage, high-current electrical discharge that occurs at the instant two points, through which a large current is flowing, are separated.
A continuous flow of electrical current, visually recognizable as a yellow flash, between an electrode and workplace. An arc will damage both the electrode and workpiece.
A luminous discharge of electric current crossing a gap between two electrodes either through the air or over an insulated surface. An effect which proves deleterious to electromechanical switches which consequently limits contact life.
The flow of electric current across a gap in a circuit which causes a light or a glow.
Sparking that results when undesired current flows between two point of differing potential.
A spark between two electrical points.
See Arc discharge.
The physical gap between the end of the electrode and the base metal. The physical gap causes heat due to resistance of current flow and arc rays.
A high temperature luminous electric discharge across a gap.
The luminous discharge of electricity between two electrodes in HID lighting.
A light caused be electricity jumping from one point to another through open air.
Sparking that results when undesirable current flows between two points of differing potential. This may be due to leakage through the intermediate insulation or a leakage path due to contamination.
electricity conducting through the air itself. Used in welding metals, but also caused by loose connections or conductors too close to each other and/ or other materials. 12 volt DC can arc a 1/4", while 100,000 volts (Lightning) can arc thousands of feet. Within the arc, air turns into a plasma that has much lower resistance than normal. Drawing an Arc, starts by making full contact between electrical connectors, and while current is flowing slowly pull the connectors apart. The arc can burn these contact points badly if sustained for more than a split second. AWG: (American Wire Gauge), standard for wire sizing in the United States. Formerly known as Brown & Sharp. Wires are sized from #40 (smallest) to #0000 (4/0) largest. See wire & connectors guide for comparison table.
The area in which electricity jumps from the electrode to the workpiece. The heat generated by the arc melts the base metals.
A spark resulting when current flows between two points that are not connected by an intentional conductor.
A prolonged electrical discharge between two electrodes.
The flow of an electric current across a gap between two conductors, terminals or contacts. Can result in sparks, a loud noise and a momentary or sustained outage as protective equipment operates.
The flow of electric current across a gap in a circuit that causes a spark, light, or glow. Generally not considered to be a good thing.
