| has gloss | (noun) the gap between two high-potential terminals spark gap |
| has gloss | eng: A spark gap consists of an arrangement of two conducting electrodes separated by a gap usually filled with a gas such as air. When a suitable voltage is supplied, a spark forms, ionizing the gas and drastically reducing its electrical resistance. An electric current then flows until the path of ionized gas is broken or the current reduces below a minimum value called the holding current. This usually happens when the voltage drops, but in some cases occurs when the heated gas rises, stretching out and then breaking the filament of ionized gas. Usually the action of ionizing the gas is violent and disruptive, often leading to sound (ranging from a snap for a spark plug to thunder for a lightning discharge), light and heat. Spark gaps were used historically in early electrical equipment, such as spark gap radio transmitters, electrostatic machines, and x-ray machines. Their most widespread use today is in spark plugs to ignite the fuel in internal combustion engines, but they are also used in lightning arrestors and other devices to protect electrical equipment from high voltage transients. |

| has gloss | deu: Eine Funkenstrecke ist der Entladungsraum zwischen zwei Leitern (Elektroden) in dem sich ein Gas (zum Beispiel Luft) befindet. Steigt die Spannung zwischen den beiden Elektroden auf die Überschlagspannung an, so führt das entstehende elektrische Feld zu einer Ionisation des im Entladungsraum befindlichen Gases, dieses wird leitfähig und die Strecke wird aufgrund der Stoßionisation innerhalb von Bruchteilen einer Mikrosekunde durch einen Funken (kurz)geschlossen. |

| has gloss | nor: Et gnistgap er en elektrisk innretning som leder strøm ved en fastsatt overspenning. Den er laget for å beskytte for eksempel et elektrisk distribusjonsnett mot lynnedslag, ved å lede strømstøtet fra lynet ned til jord. Den kobles i så fall mellom nøytralpunktet på transformatoren og jordlederen. |

| has gloss | pol: Iskra - odmiana wyładowania elektrycznego w atmosferze lub innym gazie o podobnym ciśnieniu lub cieczy. Iskra elektryczna od łuku elektrycznego różni się dużym oporem elektrycznym kanału przewodzącego. Ze względu na własności fizyczne iskrę elektryczną można podzielić na: * iskrę krótką * iskrę długą Specyficzną odmianą iskry jest tak zwana iskra ślizgowa, czyli wyładowanie elektryczne po powierzchni izolatora. Spektakularną odmianą iskry jest piorun. |
