Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFWhen high voltage is applied between the electrodes, the air between them gets ionized, forming a plasma. This plasma allows electric current to pass continuously through it, sustaining the arc and producing heat. Without ionization, the arc would be extinguished.
Other options like dielectric strength of air resist arc formation, magnetic field may influence arc movement but not its sustainment, and heat conduction does not contribute to maintaining the arc.
