Circuit Analysis Techniques in Multisim: Lab Report and Analysis

This week's lab involves applying circuit analysis techniques to a resistive circuit using Multisim. The focus is on performing mesh analysis to determine the current and power supplied by a voltage source, both with and without an dependent current source. The task includes constructing the circuit in Multisim, conducting simulations, recording measurements, and analyzing the effects of removing the dependent source. Additionally, the report requires answering interpretive questions related to the measured versus calculated values and the distribution of power within the circuit.

Understanding the fundamental principles of circuit analysis is essential for designing and troubleshooting electrical systems. In this laboratory exercise, the application of Kirchhoff's Voltage Law (KVL), Kirchhoff's Current Law (KCL), and Watt's Law provides a comprehensive understanding of how power is distributed and conserved within resistive circuits. The primary goal is to analyze a specific circuit from exercise 48 in Chapter 4, which involves calculating currents and power using theoretical methods, then validating these calculations through simulation in Multisim.

The initial step involves constructing the circuit that includes resistors, a 1V power source, and a dependent current source '5i1'. The circuit diagram corresponding to Figure 4.73 from Chapter 4 serves as the template for this exercise. Using established circuit analysis techniques, the calculated current 'i1' and the power supplied by the source are determined. Subsequently, the same circuit is modeled and simulated in Multisim to measure actual current and power values. These measurements offer insight into the accuracy of theoretical calculations and highlight real-world variations due to component tolerances.

Moving forward, the dependent current source '5i1' is removed from the circuit, and the simulation is rerun to observe how the absence of this source affects the current 'i1' and the power supplied by the 1V source. The direct comparison of measurements before and after removal provides valuable understanding of the influence of dependent sources on circuit behavior. Measurements are recorded with resistors set to 5% tolerance to reflect realistic component variability. Screen captures of these measurements further support the analysis.

One key aspect of the analysis involves verifying the principle of conservation of energy by comparing the total power supplied by the source with the sum of power dissipated across all resistors. This involves calculating power for each resistor (using P=IV or P=I^2R) and confirming that these sum to the power supplied, as mandated by Watt's Law. Discrepancies between calculated and measured values are examined, considering factors such as component tolerances, measurement errors, and simulation accuracy.

Furthermore, the exercise explores the impact of removing the dependent source on the overall circuit behavior. This includes analyzing whether the total power supplied or dissipated changes significantly and understanding the role of dependent sources in controlling circuit parameters. These insights contribute to a deeper understanding of circuit dynamics and the importance of dependent sources in circuit design.

The final step involves compiling all findings into a comprehensive Word document titled “Lab2_StudentID.docx,” including the analysis, simulation results, tables of measured data with units, and relevant screenshots. The report rigorously answers the set questions, demonstrating comprehension of the underlying principles and the practical application of circuit analysis techniques in Multisim. Proper APA citation of scholarly sources further supports the theoretical background and contextual understanding of the concepts involved.
