When measuring by measuring copper access, voltage and current between the joint joint between the length measured in the calculation of the resistivity of p=RS/L, L in the end choose which ah...
Double bridge measurement of low resistivity value of copper is 1.75 * 10-8 (*m), at the time of measurement, through the copper access circuit length and cross-sectional area of the copper resistance roughly estimated. Resistance R= P L/S, which is L P resistivity, length, cross-sectional area is S.
