Name: Jonathan Fierro GID: G00304033 Lab 2: Circuit Analysis Techniques in Multisim Grantham University Date: February 23, 2024
Introduction: This lab is intended to explore the application of circuit analysis techniques to a resistive circuit in Multisim. A mesh analysis using Kirchoff’s voltage law will be performed on the current loops within the circuit to determine currents and power delivery and dissipation. The first circuit analysis will incorporate a dependent current source equal to 5 times i1. In the second circuit, the dependent current source will be removed. The results will be compared to observe any change in the power delivered and power dissipated. Equipment/Components: Multisim Power supply: 1V, 8V Dependent current source: 5i1 Resistors: 4Ω, 3Ω, 1Ω, 2Ω Agilent multimeter Wattmeter Procedure: The following screenshots show the Multisim circuits to be analyzed:
Calculations with dependent source (5i1): Mesh 1: 1 + 4 i 1 + 3 ( i 1 i 2 ) + 1 ( i 1 i 3 ) = 0 8 i 1 3 i 2 i 3 = 1 Dependent source: 5 i 1 i 2 + i 3 = 0 Super mesh: 1 ( i 3 i 1 ) + 3 ( i 2 i 1 ) 8 + 2 i 3 = 0 4 i 1 + 3 i 2 + 3 i 3 = 8 After solving system of equations: i 1 = 19 A i 2 = 61.5 A i 3 =− 33.5 A Power supplied: P 1 V = Vi 1 = 1 V ( 19 A ) = 19 W Calculations without dependent source (5i1): Mesh 1: 1 + 4 i 1 + 3 ( i 1 i 2 ) + 1 ( i 1 i 2 ) = 0
