Lab-in-a-Box Experiment 3: Ohm’s Law Name: ____________ Pledge: ____________ ID: ____________ Date: ____________ Procedure: V 1 D C = 9 R 1 1 k R 2 = ( R e d , B l a c k , B r o w n ) 0 A B D C Figure 1: Circuit for verifying Ohm's law. Analysis: 1. Identify the unknown resistor shown in Figure1. What value does the color scheme “Red Black Brown” stand for? 2. Calculate the current ABI flowing through the unknown resistor and the voltage ABV across it. 3. What is the purpose of the 1 kΩ resistor? Measurements: 4. Construct the circuit shown in Figure 1 on your breadboard. Note that the 9V source is provided by the ANDY board. 5. Plug the black DMM probe into COM and the red probe into V. Set the switch to the lowest volts scale that will not overflow for the expected voltage. 6. Measure the voltage ABV across the unknown resistor. (See Section 2.5 for good technique.) Make sure your polarities are correct. Be sure to include your units! 7. Disconnect the wire from the unknown resistor to ground (wire BC). 1 of 2
