Summarize, in a couple of sentences, the purpose of this laboratory, the procedure done, and any anticipated results.

ABSTRACT

Summarize, in a couple of sentences, the purpose of this laboratory, the procedure done, and any anticipated results.

INTRODUCTION

Describe, in your own words, of the technical principles studied in this laboratory.

PROCEDURE

Describe on your own words the procedure followed in lab. If required, make reference to diagrams and schematics. Use a paragraph format (no bullet points).

RESULTS

Describe and present the results obtained during the experimentation through graphs and tables.

Start this section with a description of your results before presenting any calculated or measured values. Provide one example of your calculations.

ANALYSIS

Explain your results and discuss their meaning and other general observations. Although the main objective of this section is not to calculate the percentage of error, it is correct to explain discrepancies if obtained results do not follow expected trends. Elaborate on the thought process that you follow to achieve a conclusion. Mention what is your main take away point(s) from this lab.

This is the most important section of the lab report, because it demonstrates the level of understanding of the concepts studied.

CONCLUSIONS

Summarize the technical findings of this laboratory report in a couple of sentences. This section does not present any new information in addition to what is already stated elsewhere in the report.

Lab 2 Nodal Analysis Objective Use nodal analysis to solve for potentials at different nodes in a circuit. Equipment • Variable Power Supplies • Digital Multimeter (DMM) • Proto Board • Connecting Probes • Resistors: 330 Ω, 470 Ω, 680 Ω, 1 kΩ, 2.2 kΩ, 4.7 kΩ • Potentiometer (variable resistor): 1 kΩ Procedure 1. Nodal analysis in Circuit 1 a. Use nodal analysis to solve for Va and Vb in Circuit 1. b. Solve for individual resistor currents using measured resistance values. c. Demonstrate the accuracy of your calculations by measuring the voltage at each one of the non-reference nodes, and current through each resistor. 2. Equivalent resistance in Circuit 1 a. Calculate the equivalent resistance of the circuit using measured resistance values. b. Calculate the current across the voltage source. Confirm that this current has the same value as the current across the resistor R1 calculated in step 1b. c. Demonstrate the accuracy of our calculations by measuring the current in a circuit consisting of two elements: source V1 and the equivalent resistance. Figure 1. Circuit 1.

3. Nodal analysis in Circuit 2 a. Use nodal analysis to solve for Va, Vb, and Vc in Circuit 2 using measured resistance values. b. Solve for individual resistor currents. c. Demonstrate the accuracy of your calculations by measuring the voltage at each one of the non-reference nodes, and current through each resistor. Figure 2. Circuit 2.
