Thevenin Equivalents

Obejective: Investigate the Thevenin value of volatage and resistance of the load from two models, the original and one simplified setup. Then we will find the maximum power that will be supplied by the system.

1. We used source transformation to find the Rth:

2. We used nodal analysis to establish the open circuit voltage:

3. We calculated the Vy by using nodal analysis. Then we evaluated the short-circuit current and used it to find the Rth:

4. By using the equivalent circuit we determined: the smallest permissible R(L2) using a voltage divider, the short-circuit current using Ohm's Law, and the open-cicuit voltage by inspection

5. We then setup the circuit

6. Data Collection and Analysis:

Conclusion: The original and simplified circuit have a good result of Thevenin Resistance and voltage with a small percentage of difference from the theoretical value that was calculated.
