Unformatted text preview: 1 EE216 Circuit Analysis I Lecture # 16 Chapter 4 2 Node Voltage Analysis Review 1/2 Proceed in a systemic manner: Define all essential nodes ( n e ) and label them (e.g. N 1 , N 2 , etc.) One essential node having the maximum number of branches and/or the most voltage sources connected to it is selected as the reference node . Assign voltages at all essential nodes (e.g. V 1 , V 2 , etc.). These are with respect to the reference node. At each node, assume it is the most positive as compared to all other nodes and that all currents leave that 3 Node Voltage Analysis Review 2/2 Number of KCL equations is n e 1 (reference node is skipped). Solve equations simultaneously to find the voltages at every node. Once these voltages are known, the currents can be found by using Ohms law . 4 Nodal Analysis Dependant Source Example 1 5 20 2 20 2 1 1 1 =- + +- V V V V 5 10 2 8 1 2 2 2 =- + +- V V V i V 1 node 2 node Two equations two unknowns.
