Essential Node
Step 1: Number of Nodal Voltage Equations
• ne is essential nodes
• Number of nodal voltage Equations is ne-1
ne is 32 nodal voltage equations are required.
Step 2: Designate a node as the reference node.
• Suggestion: Select the node with the most branches.
Step 3:Define the Node Voltage on the Diagram
Step 4: Apply KCL
• Sum Currents Away from Essential Node
Example 4.2
Example 4.3
Supernode
• When a voltage source is between two essential nodes, we can combine these nodes to form a supernode.
