Two simulation methods of the energy transmitted by the arc roots to the electrode material are described and their results are compared together and with these found by other authors. About a copper electrode the time phase evolutions are given when a constant energy flux is applied to the contact surface. The obtained results are better for vacuum and small current. The cathode and anode result discussions lead to propositions to improve arc root models.
