where (I) is current, (V) the voltage across the discharge gap, and (R) the resistance of the medium. In air at standard pressure, the breakdown voltage for a 1 mm gap is roughly 30 kV (Paschen’s law). When this threshold is exceeded, a or spark forms, creating a short, bright channel of ionized gas.
