Electric arc - Wikipedia
网页An electric arc is the form of electric discharge with the highest current density. The maximum current through an arc is limited only by the external circuit, not by the arc itself. An arc between two electrodes can be initiated by ionization and glow discharge, when the current through the electrodes is increased.
Electric arc | Electric Discharge, Plasma & Temperature | Britannica
网页Electric arc, continuous, high-density electric current between two separated conductors in a gas or vapour with a relatively low potential difference, or voltage, across the conductors. The high-intensity light and heat of arcs are utilized in welding, in carbon-arc lamps and arc furnaces that.

网页2011年2月2日 · An electric arc is a form of a self-maintained gas discharge—i.e., a discharge which does not need an external gas ionization source for continuous burning. An electric arc burns between two electrodes: …
Electric Arc - an overview | ScienceDirect Topics
网页An electric arc is a high-electric-field-induced ionization process in a gas plasma, typically in an inert gas atmosphere like argon, resulting in a conductive path for electric current. It is commonly used in applications such …
Electric Arc - an overview | ScienceDirect Topics
网页2008年6月24日 · An electric arc is defined as a continuous, luminous discharge of electric current having a thermalized plasma and supported by thermionic emission from the cathode [1]. A plasma is a partially-ionized, electrically neutral gas, while ‘thermalized’ means that it is a hot plasma.
Electric arc - Science Clarified
网页An electric arc is a device in which an electric current (a flow of electrons) is caused to flow between two points separated by a gas. The two points are called electrodes. The one from which the current originates is the cathode.
Electric Arcs - Vocab, Definition, and Must Know Facts - Fiveable
网页An electric arc is a luminous electrical discharge that occurs when a high voltage is applied across a gap between two conductors. It is a phenomenon that can be observed in various electrical systems and devices, including welding equipment, lightning, and some types of electrical failures.
Electric Arc - an overview | ScienceDirect Topics
网页An electric arc is formed when high electric field strength (voltage gradient) over normally nonconductive material, such as a gas, causes an electric breakdown of the material, which increases the conductivity in the medium.
The Electric Arc | IEEE Journals & Magazine - IEEE Xplore
网页An arc is a discharge of electricity, between electrodes in a gas or vapor, which has a voltage drop at the cathode of the order of the minimum ionizing or minimum exciting potential of the gas or vapor.
What is Electric Arc? | Electrical4u
网页What is Electric Arc? An electric arc is nothing but a visible plasma that occurs during the breaking of the current flowing conductor at a shorter distance. Example Lightning, welding machine, short circuit etc.
