Electrical breakdown in air
WebAir capacitors have a small capacitance which usually lies between 100pF and 1nF. The maximum working voltage depends on the physical dimensions of the capacitor. A high operating voltage requires that the distance between plates is sufficient to avoid electrical breakdown of air. WebMay 7, 2024 · I have noted three different phenomena due to high electric fields in air. 1. When I run a ten-stage voltage multiplier I get sparking and crackling. 2. When I run the multiplier but current limit the output with ten 720k resistors in series, I get a violet arc that is sometimes smooth and quiet and sometimes jagged and hissy. 3.
