Turning off a source used in solving circuits with the superposition, means setting its value equal to zero. A voltage sources become a short circuit when turned off. To turn off a current source it should be replaced by an open circuit. Dependent sources cannot be turned off.

The nodal analysis is explained. Necessary steps to solve a circuit with the nodal analysis is mentioned. A free ebook about nodal analysis is also included.
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.
A 6-node circuit is solved by the nodal analysis method and powers of voltage and current sources are calculated. The system of linear equations has three equations with three unknowns.
A circuit with 3 nodes, one dependent voltage source, two current sources and three resistors is solved by the nodal analysis. The PSpice simulation result is also illustrated.
Nodal analysis method is deployed to solve a four-node circuit which has a dependent current source. The target is to find the power of the controlled current source.
The nodal analysis method is deployed to solve a circuit which has one dependent voltage source, one independent voltage source and one independent current source.
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.
