Ilmapurkaus
Ilmapurkaus, known in English as an air discharge or atmospheric discharge, refers to the electrical breakdown of air. This phenomenon occurs when the electric field in the air becomes strong enough to overcome the insulating properties of the air itself. The breakdown results in the flow of electric current, often accompanied by visible light and sound. Common examples of ilmapurkaus include lightning during thunderstorms and sparks.
The process begins with the ionization of air molecules, where electrons are stripped from atoms. These free
The voltage required for ilmapurkaus depends on factors such as air pressure, humidity, and the distance over
