Maximun Power Transfer

Objective
Use the potentiometer and logger pro to verify the the Maximum Power Theorem
(Max power occurs when R_load = R_thevenin)

Procedure 

        Part A

Measured the voltages across the potentiometer at different resistances. (15 trials)

Find the max power transfer from there.

           Data

       Part B

Connect the circuit as showed with the sensor

 Use the logger pro to graph the voltages and currents on the sensor

From the graph, we can't really see the at which point is the max power transfer.

The reason why this experiment failed was because the surrounding was too noisy, and it effected the sensor by a lot.

Conclusion
The method of sensor-logger pro fails because the environment was too noisy. We concluded that the method of Part A was the better way to find the maximum power. Although the max power did not occur at R_load = R_thevenin, we can still see the max power happened to be around that range. We conclude that the reason is because the powers supply has internal resistance and it is continuously changing. Therefore, R_load + R_r =R_ thevenin.
