What is an electric discharge?
1 Answer
An electric discharge refers to the flow of electric current through a medium, typically a gas or a vacuum, between two points with different electrical potentials (voltages). It is characterized by the movement of charged particles, usually electrons, from one point to another.
When the voltage difference between two points becomes sufficiently high, it can ionize the surrounding gas or create a conductive path through the vacuum, allowing electrons to move freely between the points. This movement of charged particles constitutes an electric discharge. The discharge may manifest as a visible spark, glow, or arc, depending on factors such as the nature of the medium, the voltage, and the distance between the points.
Common examples of electric discharges include lightning, neon signs, spark plugs in internal combustion engines, and electric arcs used in welding and cutting processes. Electric discharges can also occur in nature, such as in the form of static electricity, where charges build up on surfaces and are eventually discharged through a spark when the voltage difference becomes too great.
