Fall 2005 TECH 208 – SURVEY OF ELECTRICITY LAB EXPERIMENT #1 Department of Engineering & Design at Eastern Washington University 1. Determine the proper color bands for the following resistors:  10 k  15 k 2. Using the multimeter confirm you have the right resistors. Record your results. 3. Make a simple circuit diagram that starts with the positive supply, then goes to the 10 k resistor, then to the 15 kresistor in series, and finally back to the negative terminal of the supply. 4. Set up the circuit you made a diagram of in step 3. DO NOT connect the leads to the power supply at this time. 5. When you have completed step 4, use the multimeter to measure the total resistance of the circuit. Record your results. 6. Have the lab assistant check your results of step 5. 7. Set the power supply to 30 V and measure the voltage across the terminals with the multimeter. Record your results. 8. Connect the circuit to the power supply. 9. Measure the voltage at the input connections of the circuit. Record your results. 10. Measure the voltage across each of the resistors. Record your results. 11. Adjust the voltage of the power supply to the values below and repeat steps 9 and 10.  5 V  10  15 V  20 V  25 V 12. Turn the power supply OFF and redraw the circuit diagram to allow for measurement of the current of the circuit. Modify the wiring of your lab setup to comply with your new diagram. 13. Have the lab assistant approve your setup. 14. Turn the power supply ON and measure the current flow at the same voltages used before (5 V, 10 V, 15 V, 20 V, and 25 V). Record your results. Turn OFF the power supply. 15. Examine and graph your data. What conclusions can you draw about the total resistance to the individual resistance in a series circuit? What conclusions can you draw about the change in supply voltage on the results? 16. Write a formal lab report, which is due one week from today.
