When high-voltage electricity breaks out in open air, it rips through the atmosphere, forming chaotic, branching fingers of electric plasma. These electrical arcs are difficult to control. They branch ...

Many technologies rely on electric discharge phenomena, including consumer electronics, medical devices, and high-voltage power systems. During product development, it is highly beneficial to simulate ...

Fascinating new research from atmospheric scientists at Penn State University has found during thunderstorms, electrical discharges on tree leaves can generate significant volumes of chemicals that ...

For the first time, scientists have filmed high-speed video of a phenomenon where trees emit an electrical glow by generating ...

Mars is infamous for its intense dust storms, some of which kick up enough dust to be seen by telescopes on Earth. When dust particles rub against each other, as they do in Martian dust storms, they ...

WHILE engaged on his classical experiments Hertz noticed that the appearance of the discharge between the two terminals of the oscillator was greatly changed upon the spark gap being illuminated by ...

What is partial discharge? Methods for measuring PD. How PD impacts high-voltage cables. Partial discharge (PD) is evidence of a degrading insulation system, which could trigger costly repairs and ...

Scientists have detected what they believe to be lightning on Mars by eavesdropping on the whirling wind recorded by NASA's Perseverance rover. Have you ever heard of—or even seen—red lightning? These ...

South American rivers are home to at least three different species of electric eels, including a newly identified species capable of generating a greater electrical discharge than any other known ...
