Hello all....
I am trying to figure out how you determine how much of a gap distance
between two stationary electrodes should be? For a stationary spark gap.
Is there a formula ? All responses are appreciated :)
If the distance is small compared to the radius of curvature of the
electrodes, 30 kV/cm. Hot electrodes reduce the figure in inverse
proportion. Pressure increases it in direct proportion.
If the distance is very small, the relation fails. You can´t obtain
sparks with voltages below 300 V.
