| description abstract | Purpose: This test method covers procedures for determining the electrical resistivity of copper foil. It provides for an accuracy of ± 0.30 percent of test specimens having a resistance of 0.00001 ohm (10 microhms) or more. Definition: Resistivity is the electrical resistance of a body of unit length and unit cross-sectional area or unit weight. Volume resistivity is commonly expressed in ohms for a theoretical conductor of unit length and cross-sectional area; in English units in ohm–circular mil/ft and in metric units in ohm–mm2/meter. It may be calculated by the following formula: p. = A L R where: p. = volume resistivity in ohm–circular mil/ft or ohm–mm2 /meter, A = cross-sectional area in circular mils, or sq mm, L = gauge length, used to determine R, in ft, or m, and R = measured resistance in ohms. Weight resistivity is commonly expressed in ohms for a theoretical conductor of unit length and weight. The method for calculating weight resistivity, based on resistance, length, and weight measurements, of a test specimen is given in Note 2. | |
