QUESTION 2 [12] Consider a power distribution network represented as a graph where each node represents a substation, and each edge represents a power line connecting two substations. The substations are labelled A, B, C, D, E, and F. The power lines have the following resistances (in ohms): A-B: 4 A-C: 2 B-C: 5 B-D: 10 C-D: 3 C-E: 4 D-E: 1 D-F: 6 E-F: 2 Using the given data: 2.1 Represent the power distribution network as a graph.
