Factors Affecting the Resistance of a Metal Wire

Factors influencing the resistance of metal wires are studied to influence several factors of metal wire resistance. After measuring the current and voltage, calculate the resistance using V = IR. This circuit is also used for this study, as the voltage divider circuit has better results when examining how the resistance depends on the number of identical resistors connected in series. Variables and Constants The possible variables are wire length, wire diameter, wire material and temperature.

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.

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.

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.
