Nodal Analysis

1) Label all nodes, voltages and currents.

2) Write currents in terms of voltages.

3) KCL @ each node and sub Eq. from step 2.

4) Use KVL for unknown voltage between 2 nodes. (aka V1- V2

Nodal Analysis by inspection

Unknowns = Voltages

Diagonal = Sum of conductances at each node.

Gjk = Gkj = sum of conductances between nodes j and k.

Knowns = Sum of currents sources @ node

(When current source is dependent (contains unknown variable), write out matrix eq and use algebra to move unknown variable to other side).
