# An experiment to determine resistance in relation to a wires length

## Factors affecting resistance of a wire experiment

This would have prevented the area of the wire from remaining constant and would have affected my results. Consistent with the discussion above, this equation shows that the resistance of a wire is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire. I have taken three reading and have worked out the average, shown in red. I will stand up during the investigation to ensure that I do not injure myself if something breaks. The slope reveals that when the length of a wire is increase, the resistance would go up by an approximate measurement of 1. I think that the range of my results was sufficient enough for me to draw a valid conclusion about how the length of the wire affected the resistance. The logical explanation would be that a longer wire also means that it would have more atoms, which means it will be more likely for moving electrons to collide with them; hence, higher resistance.

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.
