Because their resistance has a wide range of temperatures where it remains almost constant that’s where constantan gets its name the resistivity / conductivity of metals (and conductive/semi-conductive materials in general) usually depend on tem. Ok doing some physics coursework at the moment where i have to measure the resistivity of constantan anyway, for those who don't know, the resistivity of constantan is 49x10^-8 anyway the formula for those who don't know for resistivity is ra/l so anyway at length of 100cm, with a diameter of 0 . A wire's resistance depends on four main factors: resistivity length resistance of constantan wire coursework the wire cross-sectional area temperature of resistance of constantan wire coursework wire i will investigate how the length of the wire affects the resistance.

Assuming a constant temperature coefficient of resistivity, what is the maximum percent decrease in the resistance of a constantan wire starting at 200ºc 12 a wire is drawn through a die, stretching it to four times its original length. Experiment to measure the resistivity of a wire equipment: 1m of constantan wire of diameter 027 and 056 mm, 1m of nichrome wire of diameter 027 and 056 mm. The resistance r is the resistance wire (constantan nichrorome) that you will be trying to calculate set the power supply to 1v this limits the current through the wire in order to reduce any heating effect which may change the resistivity. The preliminary work will only involve one type of wire - constantan - the resistance of a wire introduction: in this piece of coursework, i have been finding out .
