Abstract
The present invention is directed to an apparatus and method for improving the accuracy of measuring resistivity and/or conductivity of a paste. Exemplary embodiments relate to an apparatus for measuring electrical characteristics of a material. A sample of material is placed in a first charge conducting region with a first cross-sectional area and in a second charge conducting region with a second cross-sectional area, the first cross-sectional area being greater than the second cross-sectional area. Further, the apparatus conducts an electric charge through the first and second charge conducting regions via a conductive terminal located in the first charge conducting region.
