Voltage, Current and Ohm’s Law. p. 1 Voltage, Current, Resistance and Ohm s Law Goals of Experiment: To gain familiarity with the ideas of voltage, current and resistance and to become familiar with the tools and equipment used in simple electrical measurements. Necessary Equipment 1. Resistors of various sizes 2. Digital Multimeter (DMM) 3. Protoboard 4. Voltage Supply 5. Potentiometer 6. Helipot Procedure 1. Use a DMM to read the voltage of a power supply. 2. Use the resistor color code to find a 33 k Ω and a 1 k Ω miniature carbon film resistors. Check these values with a DMM. Are the DMM readings consistent with the tolerance rating marked on the resistor? 3. The power rating of a resistor depends on its size. Using the vernier calipers measure the length and diameter of one of your resistors. Compare your measurements with the data on Panasonic 5% Miniature Carbon Film Resistors as given on the data sheet to determine its power rating. What is it? 4.
