Superposition Theorem

SUPERPOSITION THEOREM 

The superposition theorem is unquestionably one of the most powerful in the field . it has such widespread application that people often apply it without recognizing that their maneuvers are valid only because of the theorem .

Use of Superposition Theorem:

•Analyze networks that have two or more sources that are not in series or parallel .

•Reveal the effect of each source on a particular quantity of interest.

•For source of different types apply a separate analysis for each type , with the total result simply the algebraic sum of the results.

THE STATE OF SUPERPOSITION THEOREM

 

The current through, or voltage across ,any element of a network is equal to the algebraic sum of the currents or voltage produced independent by each source .

How  to  use

In the network of linear resistance containing more than one generator (or source of e. m. f) ,the current which flows at any point is the sum of all the current which would flow at that point each generators where considered separately and all the other generators replaced for the time being by the resistances equal to their internal resistances
