Resistivity of a wire coursework
There are four factors that affect the resistance of a wire: resistance is proportional to length if you take a wire of. 104 bulletinofthebureauofstandards [vol7,noi iintroduction thevaluesinusefortheconductivity,resistivity,andtempera- turecoefficientofcoppervaryconsiderablythestandardval-. Free resistance of wire papers, essays resistance of a wire coursework resistance of a wire task to investigate how the this is know as resistivity.
For this challenge lab you will be trying to determine the resistivity of a wire based on a graph of resistance vs length you will be prompted to collect 5 different current readings using 5 different length samples of wire. Resistivity and conductivity the electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made. How the length of a wire affects its resistancein my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance is the measure of how easy it is for current to flow through a wire.
Practical course: resistivity i objectives measuring the resistivity ρ for a conducting material ii determining the resistivity of a constantan wire. Physics coursework theory - resistance of a wire divided by the length of the wire the units associated with resistivity are thus ohmm (ohm - meters). Stretch the wire enough to remove any kinks or ‘slack’ in the wire 3 the resistivity values given depends on composition of the alloys used.
Episode 112: resistivity in this episode, students learn how and why the resistance of a wire depends on the wire’s dimensions they learn the definition of resistivity and use it in calculations. 262 resistance alloys and wire resistances the resistivity is about 50 × 10 −8 ω m with a temperature coefficient which may lie between ±0000 04 °c −1. Observe changes to the equation and wire as you play with the resistivity, length, and area sliders.
