). A voltage is applied to the ladder electrodes
from a transformer — say, from a neon sign,
microwave oven, or model train, or, in our case,
the output from our little high voltage generator.
If that voltage is high enough, an arc forms where
the gap between the electrodes is shortest. (For
an arc to “make the jump” across the gap, you

making it electrically conductive. The electrical
energy flowing across the arc is partly converted ...
