Breakdown potential of air
WebApr 5, 2024 · Here is a description of what happens with arcing with respect to altitude. The answer is both, the arc gap decreases from sea level to ~45 km and then increases after 45 km. However, most of us only care about 0 to 3000 m (or 3 km). The curve on the chart above tells the story. WebThe voltage required to produce an electric arc across a centimeter of air is in the neighborhood of 30,000 volts, so this arc may represent about 300,000 volts produced by the van de Graaf. The van de Graaf can also …
