Web5 apr. 2024 · An electric arc is often formed by two electrodes coming together, creating a lot of heat and then the electrodes being separated to form a small gap in which the arc is formed. The very high temperature created causes a plasma (ionised gas) to be formed between the electrodes. 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 … Meer weergeven An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma; the plasma may … Meer weergeven Undesired or unintended electric arcing can have detrimental effects on electric power transmission, distribution systems and electronic equipment.
