The incidence matrix represents the relationship between branches and nodes in the circuit. Each row of the matrix corresponds to a branch, and each column corresponds to a node. For a bipolar circuit:
- If a branch leaves a node, the entry is +1.
- If a branch enters a node, the entry is -1.
- If a branch is not connected to a node, the entry is 0.
Similarly, the resistance and inductance matrices can be constructed. You can refer to external resources to understand more on these matrices and how they are constructed.
You can refer to the following video resource that explains modelling electrical networks using ODEs and solving them:
