Two ideal dc voltage sources are connected by electrical conductors that have a resistance of , as shown in Fig. P4.102. A load having a resistance of moves between the two voltage sources. Let x equal the distance between the load and the source and let L equal the distance between the sources. a) Show that b) Show that the voltage will be minimum when c) Find x when , , and d) What is the minimum value of for the circuit of part (c)? v 5 * 10-5 1200 V, R = 3.9 , r = >m. L = 16 km v1 = 1000 V v2 = x = L v2 - v1 B -v1 ; Av1v2 - R 2rL(v1 - v2) 2 R . v v = v
