The superposition theorem states that 'The current through or voltage across an element in a linear bilateral network is equal to the algebraic sum of the currents or voltages produced independently by each source.
Equipment Required
Circuit Diagram
1. Connect the circuit as per the circuit diagram Fig.a.
2. Switch on the DC power supplies (10 V and 5 V) and note down the corresponding ammeter readings (say I A)
3. Replace the second power supply by its internal resistance Fig.b.
4. Switch on the power supply (10 V) and note down the corresponding ammeter reading (say I1)
5. Connect back the second power supply (5 V) and replace the first power supply by its internal resistance Fig.c.
6. Switch on the power supply (5 V) and note down the corresponding ammeter reading (say I2)
7. Verify the following condition : I = I1+I2.
