Investigating how the Length of Wire Affects the Resistance
I predict the resistance will be at its greatest when the wire is at its longest. This is due to free moving electrons being resisted by the atoms in the wire. In a longer piece of wire, there would be more atoms for the electrons to collide with and so the resistance would be greater. I believe this because I know that if the electrons in a current have further to travel then the resistance will increase. I also believe that the current will go down if the voltage is fixed.
I will have to follow a number of things to ensure this investigation is carried out in a fair way and that the results I get will be accurate and reliable. …
