This technique is based on Ohm’s regulation, and the measurement basic principle usually includes using 4 aligned electrodes. A number of dispositions from the electrodes are feasible, and Wenner’s a single is the most common electrode spacing approach. Electrical resistivity would be the measurement of the specific resistance of a https://raw-music66655.blogpostie.com/53983408/soil-resistivity-testing-solutions-bangladesh-an-overview
