[1] 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 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 ($${\displaystyle \Gamma _{e}(x=0)\neq 0}$$) which can be accelerated to … See more • Atmospheric pressure • Breakdown voltage • Dielectric strength See more 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 … 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. Noble gases like helium and argon are monatomic and tend to have smaller diameters.
