Resistance

... t my results are reliable, I will take the readings of each length three times. This means that I will have three sets of data for Voltage, Current and Resistance all from 10cm-100cm. I will calculate an average for each set of data and the range of results will be at 2 and 3volts.

Results:

As stated earlier, I recorded three sets of data and then calculated an average for that data. Below are my three tables and the separate table concerning the average values:

The graphs that I shall be drawing up will be of the average results for the 2 and 3 volts recordings. They shall be on separate paper as a part of the investigation.

Below are the results that I recorded at 3 volts. Again there are three sets of data for accuracy and repeatability and a separate average result table, which the graph I shall be drawing will be constructed of.
