The term electrical breakdown has several similar but distinctly different meanings. The term may apply to a failure of an electric circuit with consequent lack of function. Alternately, it may refer to the application of current to a gas. An electrical network or electrical circuit is an interconnection of analog electrical elements such as resistors, inductors, capacitors, diodes, switches and transistors. ... In electricity, current is the rate of flow of charges, usually through a metal wire or some other electrical conductor. ... Gas (actually as, part of the Gnu Binutils package) is the default Gcc Back-end. ...

The most common meaning is related to automobiles and is the failure of an electric circuit or associated device resulting in a loss of vehicle function (a breakdown). Common problems include battery discharge, alternator failure, broken wires, blown fuses, and a failed fuel pump. A small variety of cars, the most popular kind of automobile. ... Four double-A batteries In science and technology, a battery is a device that stores energy and makes it available in an electrical form. ... An alternator is a generator that produces alternating current by converting mechanical energy to electrical energy. ... 200A Industrial fuse. ... A fuel pump is an essential component on a car or other internal combustion engined device. ...

The second meaning is more specifically a reference to the breakdown of the insulation of an electrical wire or other electrical component. Such breakdown usually results in a short circuit and/or a blown fuse, but as breakdown of insulation is more generally found in extremely high voltage applications, it may cause a trip of a circuit breaker. In particular, electrical breakdown is often associated with high voltage transformers in the electricity distribution grid. Another type of electrical breakdown is found in capacitors where the applied voltage can exceed the dielectric's capability to resist and breakdown occurs. Electrical breakdown can also occur across the strings of insulators that suspend power lines or within underground power cables. Insulators are materials which prevent the flow of heat (thermal insulators) or electric charge (electrical insulators). ... This article refers to metallic wire. ... For alternate meanings see Short circuit (disambiguation) A short circuit (sometimes known as simply a short) is a fault whereby electricity moves through a circuit in an unintended path, usually due to a connection forming where none was expected. ... The difference between high voltage and low voltage depends on the situation and on the field of science or industry involved. ... A circuit breaker is a piece of equipment which is designed to protect an electrical apparatus from damage caused by overload or short circuit. ... The Transformers toys, and the related comics and animated television series which have run from the 1980s onwards. ... Electricity distribution is the penultimate process in the delivery of electric power, the part between transmission and user purchase from an electricity retailer. ... Various types of capacitors A capacitor is a device that stores energy in the electric field created between a pair of conductors on which equal but opposite electric charges have been placed. ... Transmission towers Transmission lines in Lund, Sweden Electric power transmission, or more accurately Electrical energy transmission, is the second process in the delivery of electricity to consumers. ...

Electrical breakdown can also occur in a gas (or mixture of gases, such as air) when the voltage that's applied across a gap exceeds the dielectric strength of the gas(es). The high electrical stress causes the gas to partially ionize and begin conducting. This is done deliberately in low pressure discharges such as in fluorescent lights. Electrical breakdown of the air causes a "fresh air" smell of ozone during thunderstorms or around high-voltage equipment. Although air is normally an excellent insulator, when stressed by a sufficiently high voltage, air can begin to break down, becoming partially conductive. This first occurs as a corona discharge on high voltage conductors at points with the highest electrical stress (smaller radius or sharp points). Corona is sometimes seen as a bluish glow around high voltage wires and heard as a sizzling sound along high voltage power lines. Corona can also occur naturally at high points (such as church spires, treetops, or ship masts) during thunderstorms as St. Elmo's Fire. In physics, the term dielectric strength has the following meanings: 1. ... A compact fluorescent lamp A fluorescent lamp is a type of electric lamp that excites argon and mercury vapor to create luminescence. ... Ozone (O3) is an allotrope of oxygen, the molecule consisting of three oxygen atoms instead of the more stable diatomic O2. ... In electricity, a corona discharge is an electrical discharge brought on by the ionization of a fluid surrounding a conductor, which occurs when the potential gradient exceeds a certain value, in situations where sparking is not favoured. ... St. ...

Although corona is usually undesirable, it is essential in the operation of photocopiers (Xerography) and laser printers. If the voltage is sufficiently high, complete electrical breakdown of the air can result in an electrical spark that bridges the entire gap in a blue-white flash, accompanied by a loud snap or bang. Small sparks can also be generated by static electricity. Lightning is an example of an immense spark that can be miles long. If a fuse or circuit breaker doesn't stop the current flowing through a spark in a power circuit, electricity may continuue to flow across the gap, forming a hot electric arc. Although sparks and arcs are usually undesireable, sparks can be quite useful in everyday applications such as spark plugs for gasoline engines, and arcs are used for electrical welding of metals or for creating special purpose alloys in an electric arc furnace. Xerography (or Electrophotography) is a photocopying technique developed by Chester Carlson (Born Feb 8 1906 - Died Sep 19 1968) in 1938 and patented on October 6, 1942. ... A laser printer is a common type of computer printer that produces good quality printing, and is able to produce text and graphics. ... A spark may be a small airborne ember from a fire. ... Static electricity or electrostatics is a field of science and a class of phenomena involving the imbalanced charge present on an object, typically referring to charge with voltage of sufficient magnitude to produce visible attraction, repulsion, and sparks. ... For alternate meanings, see Lightning (disambiguation). ... An electric arc can melt calcium oxide. ... This article or section should include material from Spark gap A spark plug is an electrical device that fits into the cylinder head of some internal combustion engines and ignites compressed aerosol gasoline by means of an electric spark. ... Arc welding Welding is a joining process that produces coalescence of materials (typically metals or thermoplastics) by heating them to welding temperature, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler materials. ... An alloy is a combination, either in solution or compound, of two or more elements, at least one of which is a metal, and where the resultant material has metallic properties. ... An electric arc furnace is a system that heats the charged material by means of an electric arc. ...
