Inan & Dr. Joseph P. Hoffbeck Lab Experiment #2: Simple Resistive Circuits - p. 2 of 4 - Simple Resistive Circuits I. Objective In this experiment, the students will design, build and/or experiment simple resistive electrical circuits to gain some experience in using Ohm’s law, Kirchhoff’s laws, and their extensions such as voltage and current divider principles to analyze circuits consisting of series- and parallel-connected resistors. II. Procedure PART 1: Voltage and Current Divider Principles Part 1(a): Verification of the Voltage Divider Circuit 1(a)−Pre-lab Assignment: For the circuit shown in Fig. 1(a), calculate the output voltage Vout using the voltage divider principle. 1(a)−Lab Experiment: Construct the circuit shown in Fig. 1(a). Measure and record the actual values of the resistors R1 and R2 used in your circuit. Measure and record the output voltage Vout. Check to see if your measured Vout value agrees with the Vout value calculated in the pre-lab assignment and comment. Next, use the function generator and replace the 5-V power supply voltage in the circuit with a sinusoidal voltage source Vs(t) with 5-V peak voltage (amplitude) and 10- kHz signal frequency. Observe the two signals Vs(t) and Vout(t) on the oscilloscope simultaneously. Verify that the voltage divider circuit still works. Fig. 1(a). The voltage divider circuit.
