Abstract(in English) | As size of true contact are in contact interface is very small comparing apparent area, the current which flow the true contact area is constricted. Contact resistance caused by this constriction of current is called as constriction resistance. The constriction resistance has been obtained by solving Laplace equation which gives space potential. However, it is not sufficient to determine the constriction resistance only by using potential distribution in space. This is one sidedness, interaction between the current and self-magnetic field should be taken account in consideration. Therefore, here, effect of self-magnetic field on constriction resistance was studied on both for one true contact area and two true contact areas with very close distance. Namely, effect of Lorentz force on constriction op current was deduced. As results, effect of Lorentz force is not effective for lower level current, on the other hand, for higher current, current effect is not ignored |
