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 … See more 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. It is named after See more Basics To calculate the breakthrough voltage, a homogeneous electrical field is assumed. This is the case in a parallel-plate capacitor setup. The electrodes may have the distance $${\displaystyle d}$$. The cathode is located … See more Different gases will have different mean free paths for molecules and electrons. This is because different molecules have different diameters. … See more • Electrical breakdown limits for MEMS • High Voltage Experimenter's Handbook Archived 2011-10-16 at the Wayback Machine See more The mean free path of a molecule in a gas is the average distance between its collision with other molecules. This is inversely proportional to the pressure of the gas, given constant temperature. In air at STP the mean free path of molecules is about 96 nm. Since … See more Paschen's law requires that: • There are already free electrons at the cathode ($${\displaystyle \Gamma _{e}(x=0)\neq 0}$$) … See more • Atmospheric pressure • Breakdown voltage • Dielectric strength See more WebAbstract and Figures The intersection of Paschen's curves for argon with a same gap length but a different electrode radius was observed.

WebMar 21, 2024 · 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. It is named after Friedrich Paschen who discovered it empirically in 1889..
