SUPERPOSITION THEOREM

When a number of voltage and current sources are acting in a linear network simultaneously, the resultant current in any branch of the circuit is the algebraic sum of the currents produced by activating one source at a time while de-activating the other sources. The voltage source is replaced by its internal resistance while the current source is replaced by open-circuit

This theorem is applicable only in linear circuits , i.e circuits consisting of resistances or impedances in which ohm’s law is valid.

The above theorem is applied when we are to determine the current in any particular branch of a network containing several voltage sources or current sources or both voltage sources and current sources.

EXAMPLE PROBLEM FOR UNDERSTANDING :

Use the superposition theorem to determine the current through the resistor R = 4 Ω for the network.
