    Does anyone know what is the minimum voltage to cause arcing in air,at
    normal humidity and approx 1cm apart? thanks jk

    Does anyone know what is the minimum voltage to cause arcing in air,at
    Nowhere near enough information.

    What kind of conductors are separated by approx. 1 cm. (which, by the way,
    isn't good enough, either)? Are they polished, smooth balls? Do they happen
    to have any sharp edges? It makes an enormous difference.

    What kind of voltage are you applying? Is it DC or AC, and if AC, what
    frequency?

    "Normal" humidity means what range? And at what temperature range? Are either
    or both of these controlled?

    Is the air filtered and totally free of dust?

    The maximum dilectric breakdown voltage for air is listed in any physics
    textbook (voltage at which it's guaranteed to arc over), but the minimum is
    entirely dependent on the details.

    Good luck, and keep one hand gripping your belt behind your back!

  3. Put two electrodes 1 cm apart and apply voltage until it arcs. Then you will
    know.
