Ground Resistivity Testing Bangladesh for Dummies

The sphere is imposed over the homogeneous soil sample to evaluate an exact electrical resistivity of a sample. Time variation and the real difference in electrical resistivity are lower than 0.five% when measured in the same soil sample from the cells with distinct distances among electrodes. The measurements in 4-electrode laboratory cell were us
