Theory: This is one of the
fundamental theorem: applicable to linear networks. Linear networks are those
networks which are constructed with lincar clements only. The active sources
and the passive elements like R. L. and C are assumed to be operated in their
lines ranges. The vi, relationship for these elements are lincar. The
superposition theorem states that in a linea bilateral multi source Do circuit,
the current through or voltage across any particular element may he determined
by considering the contribution of each source independently, with the
remaining sources replaced with their internal resistance. The contributions
are the summed paying attention to polarities to find the total value.
Superposition cannot in genel be applied to n lincor cirs r Nonlinear functions
such as power
Circuit Diagram:
PROCEDURE:
1.
Connect
the circuit as per given diagram.
2.
Short
circuit the Vs2 from the circuit and turn ON the supply Vs1 and measure the current
Is1 through load resistance R_{L}.
3.
Short
circuit the Vs1 from the circuit and turn ON the supply Vs2 and measure the current
Is2 through load resistance R_{L}.
4.
Turn
ON the supply Vs1 and Vs2 together and measure the current Is12 through load
resistance R_{L}.
5.
Finally
verily Is1 + Is2 = Is theoretically and practically.

I_{S1}
(theoretical) = 3.99A
I_{S2}
(theoretical) = 7.75A
%Error=0.67%
Precaucation:
1. Make
the connections properly.
2. Note
the readings of voltmeters and ammeters properly.
3. Remove
insulations from the connecting wire so as the current will flow properly.
:
Conclusion: Superposition theorem was verified and an error of just 0.67 percent was found due to the difference in measured and calculated values.
