Investigating the Factors that Affect the Resistance of a Wire

To investigate factors that affect wire resistance: It is my purpose to investigate how the length influences wire resistance. Safety: § Do not leave the battery for a long time with the power turned on. It may cause fever and may cause burns. Be careful when you touch the wire as there is a possibility that the wire is getting hot. § It is only necessary to read and remove the battery, so connect the battery to the wire only for a short time. Be careful when cutting the wire.

I think that I have successfully studied factors that affect wire resistance. You can find factors that affect resistance and write in my hypothesis how these factors affect resistance. I proved my remarks with scientific knowledge. Also, during the course of this project, I tested it by doing real experiments.

In this survey we investigate the impedance of the wire against the current and identify the factors that affect wire resistance. There are five main factors that affect wire resistance. They are as follows: 1) wire material. 2) Wire length 3) Wire thickness (diameter). 4) Temperature of the wire 5) Voltage of the circuit However, my survey shows only two different factors that affect wire resistance.

Because other factors such as temperature are difficult to control and change, I decided to investigate the influence of wire thickness on resistance. There is not enough material to study how the material affects wire resistance. The effect of wire thickness on resistance is an effective experiment. The drawing can be drawn easily, a wide range of results can be obtained, and the result can be easily recorded. The thinner the wire, the less the path of electrons in the wire, so the current will not flow easily. This will increase the resistance because the energy does not diffuse too much. If the thickness of the wire is thick, more electrons can pass through the wire, so the resistance becomes smaller. Due to the large diameter of the wire, atoms from the metal can not collide or collide with as many electrons as possible.
