Lab Day 5

Nodal Analysis Lab

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

This picture is from the pre-lab. We had to calculate the voltages from nodes 1-4 and found out that at node 2, V= -0.576V. We took this number to calculate the voltages V1 and V2 in the circuit as shown on the top right corner.

This is a picture showing the measured V1 which is equal to -2.39V.

This is a picture showing the measured V2 which is equal to -4.41V.

This is a picture showing the schematic of the circuit on the top left corner. The voltages at 4 different nodes on the bottom left. The calculated V1 and V2 on the top right corner. At last, the measured V1 and V2 on blue color.

Conclusion: After measuring V1 and V2, we calculated the percent error between the measured and expected values of V1 and V2. The percent error for V1 was 1.42% and V2 was 0.32%. This happened because the measured resistance values were a little off of what we were supposed to use.
