Brief Theoretical Description
Superposition theorem is applicable for linear and bilateral networks. Superposition theorem
states that “A linear and bilateral Network containing more than one source, the current in any branch is
the algebraic sum of current that would be produced by each source, acting alone, all other sources
being replaced by their respective internal resistances.”

Experimental Procedure
7.
1. Connect the circuit as shown in fig.1
2. Replace the V2 source by a short circuit and note the ammeter readings I1, I2 and I3.
3. Replace the V1 source by a short circuit and note the ammeter readings I1, I2 and I3.
4. Calculate the resultant of I1, I2 and I3.
5. Measure I1, I2 and I3 by keeping both the sources in the circuit and verify the answer.
