Nodal Analysis
Nodal Analysis
1. Nodal analysis can be applied for the planner and non-planner networks
2. Nodal analysis is based on the application of KCL
Note:
1. A principle node is a point where more than two branches are connected.
2. A simple node is a point where two branches are connected.
The procedure of nodal analysis:
Step 1: Identify the total no. of principle nodes
Step 2: Assign voltages to each principle node and take one of the nodes as a reference node
Step 3: Develop KCL equations for each node(except for reference node)
Step 4: Solve the KCL equations to get node voltages
A special case of nodal analysis(Supernode)
A supernode exists in a circuit when two non-reference nodes separated by a pure voltage source
The procedure of super nodal analysis:
Step 1: Identify the total no. of principle nodes
Step 2: Assign voltages to each principle node and take one of the nodes as a reference node
Step 3: If super node found, then develop KCL equation for supernode and remaining reference nodes
Step 4: Develop KVL equation for supernode
Step 5: Solve KVL and KCL equations to get node voltages
