The slope reveals that when the length of a wire is increase, the resistance would go up by an approximate measurement of 1. Two data of the largest errors went way above the predicted line, which from it we can infer that the collected data is considered to have an inconsistent precision.
Based on the information stated in the above question, explain the risk involved in using gauge wire in a circuit that will be used to power an ampere power saw.
It has been a known fact that the length of a wire is one of the four factors that has a role in the resistance of the wire, and this experiment has simply confirmed it.
Perhaps you're doing a lab and need to know the resistance of a resistor used in the lab. I will also ensure that there is a clear indication that the power is isolated by means of a switch and an L. The investigation has concluded that there is a clear relationship between the length and the resistance of a wire, and that the former does in fact affect the latter.
The maximum error bar that can be identified there is the 4th independent variable, which was the 40cm wire, and the minimum error bar was located in the 1st data, which was the 10cm wire.
