Verify superposition Theorem

Practical to verify Superposition Theorem  

Aim:- To verify superposition Theorem

Apparatus Required:-

S. No.	Name of Equipment	Type	Range	Quantity
1.	Electric Network Kit	-	-	1
2.	Ammeter	MC	0 – 100mA	1
3.	Voltmeter	MC	0 – 30 V	1
4.	Power Supply	Regulated	0-300V	1

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 v-i, 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.

Observation Table:-

S. No.	VS(V)	I1(mA) (T)	I1(mA) (P)	I2(mA) (T)	I2(mA) (P)	I1+ I2 (T)	I1+ I2 (P)	% Error
1.	4	3.76	3.80	3.99	4.00	7.75	7.3	5.80

 

Calculation:-

                                  I_s (theoretical) = 3.76A

                                 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.
