Review Node Voltage Method Chapter 4-2 Review Node Voltage Method

Node-Voltage method 1. Draw circuit with no branches crossing

Node-Voltage method 2. Count the number of essential nodes (ne ), you will need (ne -1) equations to describe the circuit,

Node-Voltage method 3. This circuit has three essential nodes 4. choose one as a reference node, typically the node with the most branches 5. Assign remaining essential nodes with node voltages, in this case nodes 1 and 2. A Node Voltage is defined as the voltage rise from the reference node to a non-reference node

6. Label the nodes and label currents as leaving the nodes, one node at a time apply KCL, using ohms law to write in terms of voltages summed to zero at the node 7. Repeat step 6 for the other nodes
