nodes 1, 2, 3, and (7 In the diagram below, each resistor has resistance R. To solve for the voltages at 4, first write Kirchhoff's law at each, stating that the total current into the node is zero (the "no-puddle theorem"). For example, at node 1, (Vi-Vo)/R+ (y-½)/R+(Vi-VJ// equations in the four unknown voltages, Vi, ½ Va and V . Solve these equations using matrix algebra. 2 0. You will get four linear
