WebPaschen’s law 1 Paschen curve Early vacuum experimenters found a rather surprising behavior. An arc would sometimes take place in a long irregular path rather than at the minimum distance between the electrodes. For example, in air, at a pressure of 10−3 atmospheres, the distance for minimum breakdown voltage is about 7.5 µm. Web2 Dec 2015 · Paschen’s Law is an equation that gives the breakdown voltage, that is the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length. Paschen studied the breakdown voltage of various gases between parallel metal plates as the gas pressure and gap distance were varied. snes9x change fast forward speed
