science corse work (minus results) GCSE Physics Coursework - resistivity of a wire Coursework Resistance of a Wire Task To investigate how the electric resistance of a wire is affected by the length of the wire. speculation What is resistance? Electricity is conducted through a conductor, in this seem wire, by means of forego electrons. The number of stop electrons depends on the material and more free electrons means a puff conductor, i.e. it has less resistance. For example, gold has more free electrons than iron and, as a result, it is a better conductor.

The free elect rons are tending(p) zipper and as a result move and collide with neighbouring free electrons. This happens across the length of the wire and thus electricity is conducted. Resistance is the result of energy loss as heat. It involves collisions among the free electrons and the mend particles of the metal, other free electrons and impurities. These collisions convert near of the energy that the free electrons are car...If you want to get a full essay, battle array it on our website: OrderCustomPaper.com
