Before starting my coursework i have decided to chose a factor that will affect the resistance of a wire i shall do this by going through all of the factors that affect the resistance of a wire and how i would measuring each factor to find out which. Physics gcse coursework:factors affecting the resistance of a wire had a high resistance, because it has a high resistance it will be easier to measure any change in resistance, and therefore get accurate results.
Given the dimensions and resistivity of a wire, determine its resistance solution is included after problem 802 physics ii: electricity and magnetism, spring 2007. 3 students should come to understand that the resistance of a wire depends on its length, its cross sectional area, and the material out of which it is made with some students you could go further and introduce the concept of resistivity ρ, through the relationship r = ρ l / a where r = resistance, ρ = resistivity, l = length and a = cross. - gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by the length of the wire theory what is resistance electricity is conducted through a conductor, in this case wire, by means of free electrons.
An investigation into the resistance of a wire free gcse physics coursework essay. I am going to be studying the resistance of wire the purpose of this investigation is to see how length and thickness of wire affect the dependent variable, resistance prediction physics coursework investigation - physics coursework investigation i intend to invest. Im doing my resistance of a wire coursework and ive done all of it apart from the last bit where i have to describe how the experiment testing the resistance of a wire could be used in a workplace i have to give a use for the experiment in a workplace and describe how the experiment is used ina workplace and expalin why it is useful.
Resistance: depends on size and shape - as well as on the material what is resistivity in effect, the resistivity represents the resistance across two opposite faces of a cubic metre of material (in the same way that density is the mass of a cubic metre. Homework help: resistance of a wire experiment oct 26, 2011 #1 peter g hi, i have to come up with five limitations in my experiment in order to then explain them this is the first time i do this, so some of my suggestions might seem absurd the fact that, as the wire got shorter and therefore the resistance greater, i could not keep the. Some students will find resistance of a wire coursework time consuming and challenging these students may decide to buy coursework as it is important to submit well written coursework if they are to avoid failing the subject.
Resistance coursework aim: my aim is to find out which factors affect the resistance of wire and how they affect them ohm's law: ohm's law is also relevant to know of ohm's law, which states that the current through a metallic conductor (eg wire ) at a constant temperature is proportional to the potential difference (voltage. I suppose companies could use the resistance to ensure the cross sectional area (the thickness of the wire) was the correct amount - a thinner wire means more resistance a company making guitar strings could put an electrical current through to ensure that the thickness was the correct amount, maybe.
Join now to read essay physics coursework theory - resistance of a wire theory behind my experiment thickness (cross sectional area of the wire), length, and temperature all have some effect on the amount of resistance created in a wire. Furthermore, the resistance of a wire is directly proportional to the length and inversely proportional to the area, so doubling the length of a wire should increase the resistance by a factor of two. The school has gave me a roll of iron wire but its a littl bit rusty, will this have a major effect on the resistance of the wire no, it will not it may, however, affect your measurement of its diameter. Class practical a simple investigation of the factors affecting the resistance of a wire.
Physics coursework investigating resistance of wires for my physics coursework i am investigating the resistance of wires when a metal wire is placed on an electric circuit the voltage from the battery makes the electrons flow through the wire. Observe changes to the equation and wire as you play with the resistivity, length, and area sliders sample learning goals predict how changing each variable will affect the resistance.
