The theory of superposition is used to analyze the circuit consisting of multiple voltage sources and prisoners.<\/span> The voltage source can be either a voltage or current source itself.<\/span> The theory of superposition facilitate determining the current on a branch with regard sources working one by one.<\/span> The total current in the branches of an algebraic sum of the currents of each source with attention to the direction of flow.<\/span><\/p>\n When working on one source, then short circuited another source (for source voltage) and open linked to a current source.<\/span> For more details see the circuit in figure 4.7 below.<\/span> To calculate the current in R2 can be done by calculating the current caused by V1 and V2 are alternately later and the scores are added.<\/span> From the picture above the current equation:<\/span> 2) Calculated currents by the voltage source V2 is I2, the equivalent circuit as shown 4.9<\/span>
