For the essence of an arc is that it should be continuous, and that the poles should not be in contact after it has once started.n electric arc differs from a glow discharge in that the current density is quite high, and the voltage drop within the arc is low; at the cathode, the current density can be as high as one megaampere per square centimeter.
