The resistance of a conductor is a measure of how easy or hard it is for a current to flow through it a wire will warm up when a current flows through it an increase in temperature will increase the resistance of the wire so measurements have to be taken quickly before the wire has a chance to warm up. Whole investigations were introduced to gcse courses which gained a bad reputation because there were many vague criteria that were officiously applied to assess success whole investigations the independent variable is the one that we change (eg by changing the length of resistance wire) the dependent. 6 wwwgcse-sciencecom gcse gateway science candidate style answers when the resistance of the wire becomes smaller it is harder for the charge to move through the wire because there is not as much room for the charges to move past the atoms in the metal bibliography. Resistance of a wire - gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by the length of the wire theory what is resistance electricity is conducted through a conductor, in this case wire, by means of free electrons the number of.
