3/16 Nodal Analysis Multiple Sources

        The purpose of this lab is to verify the node analysis. We need to find the theoretical value of current then compare to the actual current in the circuit. Then find the percent error.

1.In the space below, provide a schematic of the circuit, labeled with reference node and values for node voltages as determined in the pre-lab. Provide estimates for the voltages V1 and V2 , based on your node voltages.

Based on our calculation: V1 = 2.424V and V2 = 4.424V

2. In the space below, provide a schematic of the circuit being testing, including measure resistance values.

The test resistance is 1.66K

3. Provide your measured values for the voltages V1 and V2. Provide a percent error between the measured and expected values of V1 and V2. Comment on any significant differences between the measured and expected values.

Measured value: V1 = 2.37V, V2 = 4.34V

percemt error: V1 = 2.22%  V2 = 1.90%

Summary

      In today's class, we learned how to use the node analysis. In each node, the amount of current follow in and out have to be the same.
