1 Nodal Analysis Background KVL + KCL + Ohm’s law sufficient in analyzing any resistive circuits difficult to use as the complexity of circuits increased Nodal Analysis Mesh Analysis developed based on Kirchhoff’s laws provide two systematic methods for describing circuits Nodal Analysis • In nodal analysis, the circuit variables are node voltages i A i B R 1 R 2 R 3 Steps to Determine Node Voltages 1. Select a reference node. 2. Assign node voltages to the other nodes. 3. Apply KCL to nonreference nodes --- express currents in terms of node voltages. 4. Solve the resulting linear equations.

2 Nodal Analysis • Node voltages – The voltage at the reference node is assumed to be zero We select node voltages as being positive w.r.t. the reference node If the node voltage is actually negative w.r.t. the reference node, the analysis will indicate it. • Once node voltages are known, we can calculate any branch current.
