Investigation to measure the resistivity of graphite essay sample aim the aim of the experiment is to find out the resistivity of graphite the resistance which is measured in ohms of a resistor is applied with three basic elements. Nichrome is commonly wound up into coils and used in heating elements (devices that convert heat into electricity through joule heating) such as hair dryers, toasters and ovens however, nichrome wires are not used as much as copper wires (resistivity = 17 × 10 −8 ωm) due to the high cost of chromium.
The problem with measuring the resistivity of copper wire is due to the properties of copper as a material copper naturally has a low resistance due to it being a superconductor, meaning that it only has a resistance of minute amounts.

Resistivity of a wire watch using the resistivity of constantan wire that you have found on the internet should essay mills be illegal. Copper wire resistivity problem does temperature affect the resistively of different sized copper wires hypothesis i think that the resistively will increase with higher temperatures because with higher temperature, resistively is higher due to the fact the atomic lattice structure increases. Resistivity is a property of a wire linking the cross sectional area and lengths of a piece of wire resistivity is the measure of resistance to flow on a molecular level. The ratio of resistivity’s of two materials a and b is 1:2, ratio of their length is 3:4 and if the ratio of radii is 2:3 find the ratio of resistance of a and b we will write a custom essay sample on. There is no possible way to tell the exact electrical resistivity without knowing the exact composition of the wire and this is because resistivity is a property that is specific to the composition of the conductor and slight changes in the composition can produce significant changes in the value for the resistivity of the conductor.
