The current dependence of the contact resistance was analyzed with special attention given to Joule heating. It was found that as the hardness of the real contact area was proportional to I-2, the real contact area was proportional to I. Therefore, the contact resistance has I-1 characteristic at the contact temperature of 2θs or 0.62θm.
