Node-Voltage Analysis with a Dependent Source First, we write KCL equations at each node, including the current of the controlled source just as if it were an ordinary current source.

Next, we find an expression for the controlling variable i x in terms of the node voltages. Example 2.9
Substitution yields: Example 2.9
