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. [2] [3] It is named after Friedrich Paschen who discovered it empirically in 1889. [4]
Townsend's early experimental apparatus consisted of planar parallel plates forming two sides of a chamber filled with a gas.A direct-current high-voltage source was connected between the plates, the lower-voltage plate being the cathode and the upper-voltage the anode.
The relationship between this breakdown voltage and the pd product—where p is the gas pressure and d is the distance between the electrodes—is referred to as Paschen's law. [1] [2] For a range of gas molecules, the breakdown voltage estimated by Paschen's law has a minimum value of around pd = 1-10 Torr cm. This suggests that in order to ...
The breakdown voltage for the glow discharge depends nonlinearly on the product of gas pressure and electrode distance according to Paschen's law. For a certain pressure × distance value, there is a lowest breakdown voltage.

Mo Canady, the executive director of the National Association for School Resource Officers, an organization that provides training for officers working in schools, said he believes school resource officers can also help students establish trusting relationships with the police — a foundation that can help build goodwill between young people ...
Breakdown voltage is a characteristic of an insulator that defines the maximum voltage difference that can be applied across the material before the insulator conducts. In solid insulating materials, this usually [citation needed] creates a weakened path within the material by creating permanent molecular or physical changes by the sudden current.
