Please keep this handout, and make sure to write down (and keep) all calculations and measurements made. A brief, written lab report will be due at the beginning of the next lab session. Details of the lab report format are available on the course website. PROCEDURE 1.Using the Digital Multimeter (DMM) 1.1.The multimeter, as its name implies, is used to measure a multiplicity of electrical quantities –namely voltage, current, and resistance. To use the DMM, attach red and black cables to the appropriate inputs. First, the resistance of a few resistors will be measured. Select three different resistor values from the reels. Attach red and black cables to the DMM to measure resistance (Ω). Set the DMM to resistance mode. 1.2.For three different value resistors, measure and record the resistance in Table 1. 1.3.Each resistor uses a set of color bands to indicate its resistance. Use the provided resistor color code chart to calculate the expected resistance of each resistor in Table 1. Also calculate the percent error for each resistor as ((measured –expected)/expected*100) and record this in Table 1. Are these resistors within specification? 2.Using the DC Power Supply 2.1.The DC power supply on the lab bench can supply both fixed (5V) and variable (0-30V) voltages. This instrument provides a constant (DC) voltage, and this will serve as the primary power source for all of the circuits in these labs. Locate the fixed 5V output, and attach red and black cables to these outputs. Turn on the power supply. 2.2.
