Early vacuum experimenters found a rather surprising behavior. An arc would sometimes take place in a long irregular path rather than at the minimal distance between the electrodes. For example, in air, at a pressure of one atmosphere, the distance for minimal breakdown voltage is about 7.5 μm. The voltage required to arc this distance is 327 V, which is insufficient to ignite the arcs for gaps that are either wider or narrower. For a 3.5 μm gap, the required voltage is 533 V, … WebOct 15, 2008 · I'm given a wire with a coaxial shell of equal length with a dielectric between them of strength 1x10 6 V/m, and I subtracted the inner radius of the shell (1.5cm) from … family vacation in the mountains
