Lab Day 6

Quiz #2

We used Mesh Analysis to solve 3 unknowns with 3 equations.

Mesh Analysis III Lab

In this lab, we analyzed, built, and tested a circuit containing multiple sources. We used mesh analysis to predict the circuit behavior prior to building and testing the circuit. We then compared the measured values with the calculate values. 

On the top left corner, there is a schematic of the circuit labeled with meshes and values for mesh currents. On the bottom left corner, we have the measured resistance values. On the top right corner, are the 3 equations we came up with to solve 3 unknown currents. The values were I1=0.26, I2=-0.8, and I3=0.112 all in milliamps. We then calculated the value for V1 which was 2.45V. After all of these calculations, we built the circuit and measured that V1 was 2.43V. The percent error between the measured and expected value of V1 was 0.82%. 

This is a picture showing the circuit and the expected value of V1 which was 2.43V.

Conclusion: The percent error between the measured and expected value of V1 was 0.82%. The percent error was made because the measured resistance values were a little different. If the resistors measured the same values as we used in the calculations, then the answers would of been the same.
