Purpose:

The purpose of the experiment was to determine the resistance of unused light bulbs

Materials:

1 Light bulb socket2 Digital Multimeter4 40 Watt standard light bulbs(frosted)4 60 Watt standard light bulbs(frosted)

4 75 Watt standard light bulbs(frosted)4 100 Watt standard light bulbs(frosted)2 60 Watt standard light bulbs (clear)2 100 Watt standard light bulbs (clear)

2 150 Watt standard light bulbs (clear)Methods:

1. Find the resistance of both multimeters by crossing probes. Record.2. Find the resistance on both sides of light bulb socket by running a probe between

the side of the bulb and the terminal, and then repeat with the other terminal andthe bottom of the socket. Record.

3. Number all light bulbs 1 through 4 with a magic marker in each different wattage(or 1 and 2 for the clear bulbs)

4. Test the resistance of 40 watt bulb number 1 by holding a multimeter probe to themetal screw part, and the other probe to the metal pin at the base of the bulb.Record this resistance.

5. Repeat procedure of the same light bulb with the second multimeter.6. Repeat steps 4 and 5 and replace 40-watt bulb 1 with 40-watt light bulbs 2,3, and

4.

7. Replace bulb and test all of the 60, 75, 100, and 150-watt bulbs (both frosted andclear) in the same fashion. Record data.8. Screw the 40-watt bulb 1 into the light bulb socket. Record resistance across the

two terminals of the socket.9. Repeat with 40-watt bulbs 2,3, and 4. Record data.10.Test the 60, 75, 100, and 150-watt bulbs (both frosted and clear) in the same

fashion. Record data.11. Calculate the average resistance for different wattage light bulbs. Be sure to take

into account both multimeters and the tare reading of both the multimeter and thelight socket.

12. Plot data.13. Draw conclusions.Data/Plots:

Attached on separate sheets

Summary:

From this experiment, data was gathered about light bulbs. We found that resistance

does indeed depend on wattage. It seemed that as the wattage got higher, resistance

correspondingly got smaller. Also, we noted that the resistance was less varied in

higher wattage light bulbs.
