Question

The arc length-voltage characteristic of a dc arc is given by the equation v=24+4l where v is the arc voltage in volts and l is the arc length in mm. the static volt-ampere characteristic of the power source is approximated by straight line with no load voltage of 80 volts and the short-circuit current of 600 amperes. determine the optimum arc length for maximum power.

Answer 1

what is the question dude??
