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. The resistivity was calculated for each of the nichrome wires and was found to be very close to one another the slight difference could be due to experimental errors the 32gauge wire had a much larger resistance, while being the longer wire and had the thinner cross-sectional area. Measuring the resistivity of copper wire of different lengths in this report i will be writing about the experiment i will conduct on copper wire of different lengths. 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. Experiment to measure the resistivity of a wire experiment to measure the resistivity of a wire equipment: 1m of constantan wire of diameter 028 and 045 mm, 1m of nichrome wire of diameter 028 and 045 mm.
Substituting the literature value for nichrome's resistivity and formula #2 into formula #1, the following equation can be obtained: this equation can graphically represented by l on the y-axis and r on the x-axis. Resisitivity through copper wire essay resistivity of copper wire of different lengths in this report i will be writing about the experiment i will conduct on copper wire of different lengths. Category: papers title: measuring the resistivity of a wire investigating the resistance of a wire essay - investigating the resistance of a wire planning ----- aim the aim of my investigation is to investigate how length affects the resistance of a wire.
Cirris systems provides you with a calculator to measure wire resistance learn more about wire resistance calculations here, and visit cirris systems today. 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. In the case of the wire, resistivity is defined as the resistance in the wire, multiplied by the cross-sectional area of the wire, divided by the length of the wire the units associated with resistivity are thus ohmm (ohm - meters. Resistivity is expressed by the greek letter rho, ρ, and is a key factor in determining the resistance of a uniform specimen in an electric circuit (r = ρl/a, with l representing a length and a representing a cross sectional area) resistivity is measured in ohm eters (ωm.
If the metal of the wire varies, the resistivity will vary control length of wire: if length increases, resistance increases as the electrons have further to travel, so more collisions will occur on the way. Man on wire essay their lives and throw you away when they don't need you anymore philippe petit, the main character of the documentary film man on wire, directed by james marsh, is a great example of such a sucker. 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. An essay or paper on electrical resistance: an overview resistance, in electricity, is a property of any object or substance to resist the flow of an electrical current the quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. 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.
More essay examples on material rubric experimental measurement of electrical resistivity of a metallic wire introduction: resistivity is a very important property of materials - resistivity of metallic wire essay introduction. 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.

The resistance of a wire is given by the equation r = ρl / a where ρ is the resistivity of the metal from which the wire is made, l is the length of the wire and a is its cross-sectional area. An investigation into factors affecting resistance of a wire essay - an investigation into factors affecting resistance of a wire plan: the possible variables i could use to find out factors affecting resistance are material wire is made of, length of wire, temperature and cross sectional area of wire.
