Objective:

To verify Superposition Theorem Lab Experiment on Breadboard

Apparatus:

  • Power Supplies : E1=12V and E2=0-12V
  • BreadBoard
  • Jumper Wires
  • DC Voltmeter 0-15 V
  • DC Ammeter
  • Digital Ohmmeter
  • Resistors : R1=in KΩ,1/2W; R2=in KΩ,1/4 W , R3 = in KΩ 1/4W

Procedure:

  1. Make up the circuit shown in the figure.
  2. Measure the resistance of each resistor and voltage of source, calculate the source current and record him in table-I.
  3. Measure the voltage V, across R3 and the current I, through it and record it in table-II.
  4. Remove E2 and replace it with a short circuit.
  5. Record the magnitude of the current I” through R3 and the voltage across it V” in table II.
  6. Remove E1 and replace it with a short circuit.
  7. Measure the voltage across R3 and the current through it and record it in table-II.
  8. Add V and V”. Also add I, and I”
  9. Compare the sets of values.

Analysis, Deduction and Conclusion:

  1. Has the superposition theorem been verified?
  2. What facts determined from the result of this experiment support this decision?
  3. Do the experimental results compare favorably with those calculated?
  4. What could be some of the cause for discrepancies?
  5. How this theorem helps in Analysis?
