To determine the location of the damage to the insulation of a two-wire telephone line with a length of L = 5 km, an EMF source with e = 10 V was connected to one end of it. It turned out that if the wires at the other end of the line are open, the current through the source is I1 = 2 A; and if short-circuited, then the current through the source is I2 = 3 A. Find the insulation resistance at the point of damage. The resistance of each line wire is R=2 Ohm. Neglect the internal resistance of the source.
