Volts versus current 

This is a comparison of different wires. Initially our wire had more length then another group that had a smaller wire. The data above depicts the material and supplies we used in this experiment. The graph on the left depicts that the longer the length the larger the resistance. The graph on the right depicts that the larger the area the more resistance.  

The data above is a comparison of two different spools of wire that we calculated. group one (our group) had a longer spool then the other groups.

The chart above depicts a volts versus Current graph. The top line would be the ours groups larger spool because it was able to display a larger slope. The line below depicts the other spool because its displays a smaller slope predicting less resistance.

The picture is the materials used in the experiment to measure volts and amps
