, Nodal Analysis
• Nodal analysis essentially aims at choosing a reference node in the network and then finding th
unknown voltages at the independent nodes w.r.t. reference node. The fixed-voltage nodes are calle
dependent nodes.
• For a circuit containing N nodes, there will be N–1 node voltages, some of which may be known
voltage sources are present.
• A and C are fixed nodes because VA = E1 = 120 V and VC = E2 = 65 V.
