3/21 Mesh Analysis

          The purpose of this lab is to verify the mesh analysis. First of all, we need to calculate the theoretical value of current and voltage for the circuit. Then, use the experimental method to find the actual value and compare to find the percent error.

1.In the space below, provide a schematic of the circuit, labeled with meshes and values for mesh currents as determined in the pre-lab. Provide estimates for the voltage V1 and current I1, based on your mesh currents.

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

3. Provide your measured values for the voltages V1 and current I1. Provide a percent error between the measured and expected values. Comment on any significant differences between the measured and expected values.

percent error for V1 = (5-4.98)/5 *100% = 0.4%

percent error for I1 = (0.3224-0.321)/0.321*100% = 0.44%

Summary

       In today's class, we learned how to do the mesh analysis. It is much more convenient compare to the node analysis. We have to know how many loop in the circuit; then, find the resistance and voltage in each loop and use the formula directly.
