WEBMost of the online sources say that the breakdown voltage of air is 30kV/cm. I've made a Cockcroft Walton multiplier and I can see the air breaking in between 17-18kV/cm. Only in a discussion at one online forum : , someone claimed it to be 17kV/cm. What exactly is breakdown voltage of air at STP? charge. voltage. air. dielectric. Share. Cite.

WEBFor 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, nearly twice as much.

WEBTwo different breakdown voltage measurements of a material are the AC and impulse breakdown voltages. The AC voltage is the line frequency of the mains . The impulse breakdown voltage is simulating lightning strikes, and usually uses a 1.2 microsecond rise for the wave to reach 90% amplitude, then drops back down to 50% amplitude after 50 ...

WEBFrom engineering and physical tables, the typical range for the breakdown voltage in air is expected to be 20 kV to 75 kV. There are other factors that influence the breakdown voltage in air, e.g., humidity, thickness, and temperature, hence the wide range.

WEBAcross relatively small gaps, breakdown voltage in air is a function of gap length times pressure. If the voltage is sufficiently high, complete electrical breakdown of the air will culminate in an electrical spark or an electric arc that bridges the entire gap.

WEBUsing Paschen's Law, the minimum breakdown in air is calculated to be 327 V at standard atmospheric pressure. This occurs at a distance of 7.5 µm. Below is the “Paschen Curve” for air, two flat parallel copper electrodes, separated by 1 inch, for pressures between 3x10-2 Torr and 760 Torr.

WEBThe voltage required to produce an electric arc across a centimeter of air is in the neighborhood of 30,000 volts, so this arc may represent about 300,000 volts produced by the van de Graaf. The van de Graaf can also be used to excite spectral tubes with specific gases in them and will display the characteristic colors for those gases.
