Unformatted text preview: 0.79V. When the current was 89 milliamps the voltage drop was 0.95V. The observed value for the resistor was calculated. We found it to be 11. The actual value for the resistor is 10 + 5 percent. We had the color code of brown-black-black-gold. This value was found through online. So we did observed-actual/actual. So 11-10.5 = 0.5. Then 0.5/10.5 times 100. You find the percent error to be 4.8%. Akshay Patel Period 10 4/2/11 There are many possibilities for sources of error. There is a possibility that we read the ammeter incorrectly. The instructor told us to read guess the ones place. The needle being in between the dashes was tough to read. Also there may have been some trouble with the batteries or the voltage meter. The readings may not always be precise. This is due to the battery being defective. The graph we plotted showed there is much error. We graphed the voltage vs. the current the relationship that we studied throughout this lab....
