Resistance of a wire - physics coursework gcse extracts from this document it proved that changing the length of a wire does indeed affect the resistance flowing through it in a positive proportional way and although there is room for further investigation resistance of a wire coursework.
What physical factors related to this piece of wire do you think are responsible for the amount of its total resistance consider a random length of wire composed of some unknown material. The resistivity of the wire will not change with the change in length resistivity is a property of the wire, it doesn't depend upon it's length or cross-sectional area however, if you are asking about resistance, it will increase to 4 times it's. • inductive effects can be ignored if the resistance of the wire is substantial — this is for instance the case for long aluminum wires with a small cross-section — or if the where w and l are respectively the width and length of the wire, and t di.
