Investigating Resistance Electricity is the flow of electrons. Resistance is the slowing of this flow. Resistance will increase when there are more electrons for the current to collide with. It will also increase when the electrons are moving at a high speed. There are five main factors that affect resistance. These are i.Length of wire ii.Temperature of wire iii.Voltage that is used to push current around circuit. iv.Thickness of piece of …

…displayed the results on a screen. This way there would be less chance of human error when noting down the results. I would also use a "slide-and-click" system when measuring the length of the wire. This would eliminate the possibility of human error when measuring the length of the wire.
