## Superposition Problem with Four Voltage and Current Sources

A circuit with two voltage sources and two current sources is solved by the superposition method. The contribution of each source is calculated individually and the response is found by adding the contributions.

## Turning Sources Off

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.

## Nodal Analysis

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.

## Nodal Analysis – Circuit with Dependent Voltage Source

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.
