Sähkökaari
Sähkökaari, often translated as electric arc, is a phenomenon that occurs when a sufficiently high voltage is applied across a gap between two conductors, causing the insulating medium, usually air, to break down and become conductive. This breakdown results in a continuous, luminous electrical discharge. The process begins with ionization of the gas molecules in the gap, which then allows for the flow of current. The intense heat generated by the current vaporizes the material at the electrodes, further contributing to the plasma state of the arc.
Electric arcs are characterized by high temperatures, often reaching several thousand degrees Celsius, and they emit
Sähkökaari has both beneficial and detrimental applications. In industry, it is utilized in electric arc welding,
