Resistance Of Wire Investigation (length)

Plan In this investigation I am expiry to investigate how the continuance of a function of cable affects its resistance. The future(a) are whole covariants that affect the resistance of the conducting fit out: - The burdensomeness of the wire is a big variable as the gauze-like the wire the large the resistance. This is beca do the current has to squeeze through a thin wire, tho it can easily bunk through a thicker one. - The space of the wire is likewise a big variable as the longer the wire the more(prenominal) atoms the electrons result hit fashioning it a bigger resistance. - The temperature of the wire results the resistance because as it gets hotter the atoms inside it vibrate more which increases the guess of the electrons hitting them so the hotter it gets the more resistance it has. - The type of wire can also affect the resistance because different metals stand different amounts of bountiful electrons and the more the smaller the resistance is. T hese variables bequeath all effect my investigation but I am going to use the continuance of the wire as the variable and keep the others the comparable to make it a fare test. I predict that the longer the piece of wire, the greater the resistance will be.

This is due to the idea of the apologise moving electrons being resisted by the atoms in the wire. In a longer piece of wire, on that point would be more atoms for the electrons to shake up with and so the resistance would be greater. The relationship between the wire length and the resistance should be directly proportional. This is because in a wire twice the length of another wire there would be d! ouble the amount of atoms causing the resistance. An example of this would be in...
