The student engineer of a campus radio station wishes to verify the effectiveness of the lightning rod on the antenna mast (see the figure below). The unknown resistance Ry is between points C and E. Point E is a "true ground," but is inaccessible for direct measurement because the stratum in which it is located is several meters below Earth's surface. Two identical rods are driven into the ground at A and B, introducing an unknown resistance Ry. The procedure for finding the unknown resistance Ry is as follows. Measure resistance R, between points A and B. Then connect A and B with a heavy conducting wire and measure resistance R2 between points A and C.
