Choose a reference node (“ground”)Look for the one with the most connections!2. Define unknown node voltagesthose which are not fixed by voltage sources3. Write KCL at each unknown node, expressing current in terms of the node voltages (using the I-V relationships of branch elements)Special cases: floating voltage sources4. Solve the set of independent equationsN equations for N unknown node voltagesNode-Voltage Circuit Analysis MethodSlide 10EE100 Summer 2008 Bharathwaj Muthuswamy1. Choose a reference node.2. Define the node voltages (except reference node and the one set by the voltage source).3. Apply KCL at the nodes with unknown voltage.4. Solve for unknown node voltages.R4V1R2+-ISR3R1Nodal Analysis: Example #1Slide 11EE100 Summer 2008 Bharathwaj MuthuswamyR4V1R2+-ISR3R1Nodal Analysis: Example #1Slide 12EE100 Summer 2008 Bharathwaj MuthuswamySlide 13EE100 Summer 2008 Bharathwaj MuthuswamySlide 14EE100 Summer 2008 Bharathwaj
