Example 14. This question concerns an engineer investigating a faulty 10 underground electric cable. The underground cable consists of two parallel wires each of length L = 1.750 km. At a distance d from terminals 1 and 2 it develops a fault which is characterised by a resistance _Ry between the lines as 20 represented in ſigure. The resistance measured between terminals 1 and 2 is R, = 415.0n and the resistance measured between terminals 3 and 4 is R2 = 430.52 Terminals 3 and 4 are then connected by a wire of negligible resistance. The measured resistance between terminals 1 and 2 now becomes R3 = 45.52 (a) Obtain a value for the resistance R of the total length, 2L, of lines assuming Rx >> R.

A typical pacemaker delivers 60 electrically stimulating pulses per minute to a heart, where each 3.5 volt pulse lasts 0.4 milliseconds. The resistance of the heart tissue between the pacemaker electrodes is typically about 600 ohms. If the pacemaker's battery pack stores about 18 kilojoules of chemical energy (the equivalent of about 2 AA batteries) and converts its energy to electrical energy in the heart tissue with an efficiency of 35%, about how long will the battery pack last? (Hint: the answer is 24 years)
