The arc length-voltage characteristic of a DC arc is givenby the equation: V = 24 + 4L, where V is voltage in voltsand L is arc length in mm. The static volt-amperecharacteristic of the power source is approximated by astraight line with a no load voltage of 80 V and a shortcircuit current of 600A. Determine the optimum arclength for maximum power.
