%X Potential-drop-ratio IP is a variation of an old electrical prospecting method; the use of three receiving electrodes distinguishes it from conventional IP systems. The voltage ratio and phase difference between the two voltages received at adjacent pairs of electrodes are measured in an R-C bridge. A field example from W.A. compares P-D-R IP with conventional IP.
