Unformatted text preview: ext section. In nodal analysis, we are interested in ﬁnding the node voltages. Given a circuit with n nodes without voltage sources, the nodal analysis of the circuit involves taking the following three steps. Steps to Determine Node Voltages: 1. Select a node as the reference node. Assign voltages v1 , v2 , . . . , vn−1 to the remaining n − 1 nodes. The voltages are referenced with respect to the reference node. 2. Apply KCL to each of the n − 1 nonreference nodes. Use Ohm’s law to express the branch currents in terms of node voltages. 3. Solve the resulting simultaneous equations to obtain the unknown node voltages. | v v We shall now explain and apply these three steps. The ﬁrst step in nodal analysis is selecting a node as the reference or datum node. The reference node is commonly called the ground since it is assumed to have zero potential.
