Investigate factors that affect resistance

Investigation of Factors Affecting Resistance Introduction Recent physics courses are studying factors that may affect resistance and resistance. So far, resistance is the opposite of the current, it is caused by electrons colliding with atoms in the metal. When an electron collides, it absorbs the kinetic energy from atoms and vibrates quickly, so atoms become high temperature, so if the vibration increases, electrons will not pass easily.

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.

I do fair testing by maintaining all the elements that affect resistance, away from the same elements as the diameter of the wire. I will maintain the same power and input power, so it will not affect the voltage originally sent through the circuit, it will remain at 6V. The temperature did not change at room temperature. Since the wire is removed after placing it in the holder for 30 seconds, it is not affected by the rise in wire temperature. Cool the wire by cooling it for 1 minute before reusing it. Since the same constantan wire material is used, the wire has the same internal resistivity level (row) and the length remains 25 cm or 0.25 m. Since the same varistor is used and remains in the same position throughout the investigation, the resistance value does not change. The weight of the wire does not change with 125 grams. When the wire is a parts holder, the wire can not cross
