elektrilahendust
Elektrilahendus refers to the passage of electric current through a medium that is normally an electrical insulator. This occurs when the electric field strength across the insulator exceeds its dielectric strength, causing the material to break down and conduct electricity. Common examples of insulators include gases, liquids, and solids.
In gases, electrical breakdown often manifests as visible phenomena like sparks, arcs, or corona discharge. These
Electrical discharges in liquids, such as water or oil, can also occur under high voltage conditions. These
Solid dielectrics can also experience electrical breakdown, though it is often a more destructive process leading
