The student engineer of a campusradio station wishes to verifythe effectiveness of the lightningrod on the antenna mast(Fig. P18.57). The unknownresistance Rx is between pointsC and E. Point E is a “trueground” but is inaccessible fordirect measurement because the stratum in which it is located is several meters belowEarth’s surface. Two identical rods are driven into the groundat A and B, introducing an unknown resistance Ry. The procedurefor finding the unknown resistance Rx is as follows. Measureresistance R1 between points A and B. Then connect Aand B with a heavy conducting wire and measure resistance R2between points A and C.
