Learning Goal: To use the node-voltage method to solve circuits with branches containing only a voltage source. The node-voltage method is a general technique for solving circuits. Fundamentally, it involves writing KCL equations at essential nodes. When the circuit contains a dependent source, you must write a constraint equation for each dependent source, in addition to the KCL equations. When the circuit contains one or more voltage sources that are the only components in branches connecting two essential nodes, the...
