How do the properties of a wire affect its resistance? Planning To be able to answer the question, first I have to explore the factors that affect the resistance of a wire. Before choosing a factor to explore, first I have to go through all the factors that affect the resistance of a wire. However, to explain what affects resistance I have to know what it is. What is current? Current is the flow of electrons around a circuit. For an electric current to flow, there must be no gaps in the circuit. Electrons flow from atom to atom round from the negative pole to the positive. Electricity is conducted through a conductor, in this case a wire by the means of having free electrons. The number of free electrons depends on the material and more free electrons means a better conductor. For example, gold has more free electrons than iron, thus resulting in...
