Verification of thevenin’s theorem in dc circuits

AIM:

To verify Thevenin’s theorem and to find the full load current for the given circuit

APPARATUS REQUIRED:

1. RPS (regulated power supply) (0-30V)  – Quantity 2 
2. Ammeter (0-10mA) 
3. 330Ω 1k Resistors  
4. Bread Board — — 5. Wires – Required

THEORY:

Any linear bilateral, active two terminal network can be replaced by a equivalent voltage source (VTH). Thevenin’s voltage or VOCin series with looking pack resistance RTH.

PRECAUTIONS:

Voltage control knob of RPS should be kept at minimum position. 2. Current control knob of RPS should be kept at maximum position

PROCEDURE:

1. Connections are given as per the circuit diagram. 
2. Set a particular value of voltage using RPS and note down the corresponding ammeter readings

To find VTH

3. Remove the load resistance and measure the open circuit voltage using multimeter (VTH).

 To find RTH

4. To find the Thevenin’s resistance, remove the RPS and short circuit it and find the RTHusingmultimeter. 

5. Give the connections for equivalent circuit and set VTH and RTH and note the corresponding ammeter reading. 

6. Verify Thevenins theorem.
