Lecture 8:
Mesh Vs Node
Chapter 4
Techniques of Circuit Analysis: Section 4.8

2. Mesh or Node?
Q: When should we use the Node-voltage method over the mesh-current method and vice-versa?
A: Not a clear answer.
When the circuit contains supernodes or voltage sources between two nodes, use node-voltage method.
When the circuit contains current sources between two meshes, use mesh-current method.
When the circuit contains both, use your best judgement.

3. Example 4.6: Find P300Ω
Use Either Node Voltage or Mesh Current Method

4. Example 4.7: Find Vo
Use Mesh Current Method (Super Mesh)

5. P 4.54: Find P1k (in the center)
Use Mesh Current Method
