The sphere is imposed within the homogeneous soil sample to measure an exact electrical resistivity of a sample. Some time variation and the difference in electrical resistivity are below 0.5% when measured in the identical soil sample via the cells with distinctive distances between electrodes. The measurements in four-electrode laboratory https://rise99998.review-blogger.com/55193255/5-easy-facts-about-soil-resistivity-testing-services-bangladesh-described
