Experiment 3- Ohm’s Law Procedure- 1. Red Black Brown stands for 200 Ohms 2. Iab = 7.5 mA, Vab = 1.5V 3. The 1k Ohm resistor is there to take lots of current away from the unknown resistor. If the 1k Ohm resistor was not there, all of the current would be through the unknown resistor. With the 1k Ohm resistor in place, the current must be split. 4. N/A 5. N/A 6. Vab = 1.5V 7. N/A 8. N/A 9. Ibc = 7.44 mA 10. R = V/I = 1.5/7.44m = 201.6 Ohms 11. N/A 12. 198.4 Ohms 13. (Rm-Re)/(Re) * 100 = 1.59% 14. (Rn-Re)/(Rn) * 100 = .8% 15. Yes, the difference is easily within 5%. This difference is acceptable because the experimental, nominal, and measured values were all very

Unformatted text preview: similar. Conclusions-I can conclude from this experiment the validity of Ohms Law. The values that I calculated for resistance, current, and voltage by hand were all very similar to the actual values. I believe that some of the differences may have been from internal resistance on the board. It would be very difficult to produce much more accurate results than I did. Final Thoughts/Comments-This lab took me about half an hour to complete. It was a fairly simple lab, and a good hands-on introduction to Ohms Law....
