Systematic Methods for Analyzing a Circuit Nodal Analysis Mesh Analysis (Loop analysis)
Node Node = Point that connected together on the same wire V Example 3 nodes
Nodal Analysis Procedure 1. Count the number of nodes = N 2. Choose one of the nodes to be a reference node (0V) when there is no ground 3. Give the voltage for other nodes to be V1, V2, V3, … 4. Use Kirchoff’s current law on each node to form N-1 equations 5. Solve the equations to find V1, V2, V3, …
Supernode When there is a voltage source in the circuit, direct KCL cannot be used because we do not know the current in the voltage source. We will use the idea of supernode. Supernode is the method that combines 2 nodes together when using KCL. It will include the voltage source within the circle when using KCL.
