Let us summarize the method by which we obtain a set of nodal equations for any resistive circuit: 1 Make a neat, simple, circuit diagram. Indicate all element and source values. Each source should have its reference symbol 2. Assuming that the circuit has N nodes, choose one of these nodes as a reference node. Then write node voltages v1, V2,.WN-I at their respective nodes, remembering that each node voltage is under-stood to be measured with respect to the chosen reference1 .Make a neat, simple, circuit diagram.
