A 6-node circuit is solved with the nodal analysis. It contains one dependent voltage source, two independent voltage sources, two independent current sources and some resistors. The dependent causes two nodes to form a supernode.
This is a circuit with two voltage sources and two current sources. Nodal analysis method is used to solve the circuit. One of the voltage source forms a supernode between two nodes.
This is a complicated nodal analysis problem. The circuit has two independent sources and two dependent sources. A supernode is formed to solve the problem.
