Copper wire, model and equation of electrical resistance

F. Vodopivec ; Institute of Metals and Technology, Ljubljana, Slovenia

Abstract

Electrical resistance is modeled as conversion of electricity to heat with scattering of axial flux of EE quanta to heat with copper and oxygen electrons. In the derived resistance equation, parameters related to wire substructure, current density and wire temperature are considered. Wire interatoms EE travelling paths are proposed, as well. With 0,00037 wt. % O in copper wire, ASTM quoted resistance is calculated. In absence of electric current, R_c=0, then, copper atoms, J* and oxygen atoms affect the resistance by axial current, rsp quanta flux.
