Product description
The ends of the telegraph line are grounded using metal balls of radius r1 and r2, respectively (figure). The conductivity of the soil near them is equal to l1 and l2. Find the resistance R of the earth between the balls. Consider the soil in the vicinity of each of them to be homogeneous at distances greater than the radii of the balls.
