Mark Weller T10 Before starting this coursework I have to choose a factor that might effect resistance of a wire. To do this I will look at each factor and chose which one is probably the best one to use. In other words which one is simplest and easiest to use. This coursework investigation is finding out the factors that affect resistance in a wire. Resistance is voltage divided by amps. Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing resistance . Factors 1.Wire length: If the length of wire is different then electrons may have a longer way to travel so it may effect the resistance 2.Wire width: If the wires width is different then the larger the wire the less resistance is likely to increase. This is because of the increase of space gives more room for...
