Inan & Dr. Joseph P. Hoffbeck Lab Experiment #4: Electrical Circuit Theorems - p. 2 of 5 - Electrical Circuit Theorems I. Objective In this experiment, the students will analyze, construct and test dc resistive circuits to gain further insight and hands-on experience on electrical circuits as well as to verify some of the circuit theorems they learn in class such as the Superposition Principle, Thevenin and Norton Equivalent Circuits and Maximum Power Transfer Theorem. II. Procedure PART 1: Superposition Principle Pre-lab Assignment 1.a: For the circuit shown in Fig. 1, calculate the voltage V2 across the resistor R2 using the superposition principle. Pre-lab Assignment 1.b: For the circuit shown in Fig. 1, reverse the polarity of the 5 V dc voltage source and redo pre-lab assignment 1.1. R1=1.2 kΩ R3=2.4 kΩ R2=1.2 kΩ VS1=7.5 V VS2=5VV2 I2 Fig. 1. A resistive circuit excited by two dc voltage sources. Lab Experiment 1.a: Construct the resistive circuit shown in Fig. 1. Measure and record the actual values of the resistors R1, R2, and R3 used in your circuit. To verify the superposition principle, measure and record the voltage V2 for three cases:
