In a welding process, a current of 400 A flows through the arc when the voltage is 35 V. The length of the arc is 2.5mm, and the average diameter of the arc is 4.5mm. Calculate the current density in the arc, the electric field across the arc, and the electrical conductivity of the hot gases in the arc during welding.
