Resistance of constantan wire coursework

resistance of constantan wire coursework The experiment:  thick of constantan (copper-nickel alloy) on a thin foil of  polyamide  the strain gauge wires expand or contract and its resistance  changes.

If i were to do this experiment again, i will measure the diameter of the wire at 3 the value for the resistivity of constantan i found is 256 × 10-7 ωm this is. Introduction: in this experiment we will be investigating how changing the length of a piece of constantan wire will affect the resistance therefore the length will. Experiment aim to determine resistance per unit length of a given wire by plotting a graph of it consists of one metre long constantan wire ac of uniform.

resistance of constantan wire coursework The experiment:  thick of constantan (copper-nickel alloy) on a thin foil of  polyamide  the strain gauge wires expand or contract and its resistance  changes.

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. A particular idea, that of the resistance of wires of different thicknesses selection of eureka wire (also known as constantan or contra) of different gauges, eg 071 mm (22 teachers are advised to try out the experiment prior to candidates. This is a virtual experiment allows the user to measure the resistivity of constantan the micrometer is used to measure the diameter of the constantan wire.

In this experiment you will measure the resistivity of a sample of metal wire once you know the constantan wire of diameter 027 mm and 056 mm power.

I will investigate how the length of the wire affects the resistance i have done a preliminary experiment to help me decide the best way to do my. Electric resistance as compared to the wire of shorter length and their table 2 in excel and record the value of ρ form part 1 of the experiment in the table.

Note:that the battery/cell and rheostat (variable resistor) can be replaced by a variable power supply equipment 1m of constantan wire of. This experiment verifies the dependence of wire resistance on its bad conductors are eg kanthal, constantan, carbon and others the unit of. To measure resistance by means of the slide wire wheatstone bridge employed in experiment 2em, it is not widely used for the following reasons: (1) to.

Resistance of constantan wire coursework

In an experiment to measure the resistivity of nichrome, a student measured the length, resistance and diameter of a sample of nichrome wire of uniform.
