Hey y'all, here's the deal; I've been asked in Science to research the factors that could possibly affect resistance in a wire. So, any ideas? By the way, I'm offering 99 points.

Sorry but no idea..........
Factors affecting resistance in a wire...
Temperature: If the wire is heated up the atoms in the wire will start to vibrate because of their increase in energy. This causes more collisions between the electrons and the atoms as the atoms are moving into the path of the electrons. This increase in collisions means that there will be an increase in resistance.
Material: The type of material will affect the amount of free electrons, which are able to flow through the wire. The number of electrons depends on the amount of electrons in the outer energy shell of the atoms, so if there are more or larger atoms then there must be more electrons available. If the material has a high number of atoms there will be high number of electrons causing a lower resistance because of the increase in the number of electrons causing a lower resistance. Also if the atoms in the material are closely packed then the electrons will have more frequent collisions and the resistance will increase.
Wire length: If the length of the wire is increased then the resistance will also increase as the electrons will have a longer distance to travel and so more collisions will occur. Due to this the length increase should be proportional to the resistance increase.
This can be explained using the formula :R=V/I.
