High energy discharges arc due to the ionization of air, which creates a conductive path that is less resistive rather than the shortest route. The ionized air rises from joule heating, contributing to the arc's shape and behavior. The glowing effect of the arc is attributed to the high energy of the ionized particles, which move rapidly. The arc forms between conductive electrodes, generating extreme temperatures capable of melting or vaporizing materials. Overall, the behavior of electric arcs is influenced by nonlinear patterns of current and electric fields.
