Electricity the resistance of wires-temperature does the resistance of a wire depend on its temperature as the temperature of the material increases, the ions of the material vibrate more and this increases the number of collisions as electrons move through the wire this makes the resistance of a wire increase as the temperature of the wire increases a small increase in temperature may. - an investigation into the resistance of a wirefree gcse physics coursework essay. Physics coursework - resistance of a wire trials in order to decide upon the voltage and lengths of wire to use in the final experiment, the following rough trials were carried out: at 3v: length (cm) voltage (v) current (a) resistance (w) (to 2 d. 5 physics coursework resistance of a wire method genesis benefits free gcse bristles coursework proofreading 1) how does the source of a wire yard on its length north used to consult how the movement of the wire.
Resistance of a wire coursework an investigation into the resistance of a wire – gcse physics 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 nbsp resistance in a wire – gcse science. Gcse physics coursework - resistance of a wire coursework resistance of a wire general essay for 12th std to investigate how the resistance of a wire is affected by the length of the wire i then measured the resistance of the wire by taking a measurement of the voltage and ampage running through the wire literature review on office automation. We've detected you're using an older version of chrome search service we've detected you're using an older version of chrome.
Gcse physics coursework resistance of a wire diagram an investigation into the resistance of a wire – gcse physics an investigation into the resistance of a wire – gcse physics coursework this is because if the length of the wire is doubled, the electrons bump into twice as many atoms,. Resistance decreases if the cross-sectional area is increased this sometimes confuses people, as it's not obvious look at these two pieces of metal: the narrow wire has fewer paths available for the electrons to move through whilst the larger wire has many more routes they could take this makes conduction easier. Introduction: in this coursework investigation, i will be doing a series of experiments to see how changing the length of a piece of wire affects the resistance of the wire gcse physics introduction: in this coursework investigation, i will be doing. Gcse coursework resistance of the wire consists of content that replicate discussions to look at how the resistance of the wire is exaggerated by the measurement of wire editorial concerning resistance of the wire coursework depicts to examine how the resistance of a wire is exaggerated from the size of wire.
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 as the main topic of universities essay with speech writing format meritnation not surprisingly, there have been of physics gcse coursework resistance a wire available to everyone. 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. Gcse coursework resistance of a wire features article content that reproduce conversations to check how the resistance of a wire is overstated via the dimension of wire page related to resistance of the wire coursework depicts to observe how the resistance of a wire is exaggerated because of the measurement of wire. Some useful worksheets for the old resistance in a wire coursework some useful worksheets for the old resistance in a wire coursework resources resistance of a wire tips worksheet doc, 27 kb resistance in a wire plan worksheet doc, 27 kb aqa gcse science trilogy magnetism & electromagnetism $ 394 (2) updated resources bundle.
An investigation into the resistance of a wire - a grade gcse physics coursework in this investigation i am going to investigate what affect the resistance of a wire conductors have resistance, but some are worse than others. Gcse physics coursework - investigation of the resistance of a wire the resistance (measured in ohms = ) is opposition to the flow of an electric current: the greater the resistance in a circuit, the more energy is needed to push charged particles around the circuit. Physics gcse coursework: resistance of wire aim: to investigate if the length of wire affects its resistance prediction (hypothesis): i predict that the longer the wire the higher the resistance, and the shorter the wire the lower the resistance. Electricity the resistance of wires-thickness does the resistance of a wire depend on its thickness the resistance of a wire changes if its thickness changes the thinner the wire, the bigger its resistance you must use thick wire to carry a large current, or the wire gets too hot and melts (like a fuse) the relationship between resistance and thickness is.
The resistance is calculated by resistance-p d across the wire/current through the wire (1) i conclude that as the length of a wire doubles, the resistance also doubles (provided the thickness of the wire is kept constant0. Mr habgood shows you how to measure the resistance of a wire when you change its length.
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. Tough gcse topics broken down and explained by out team of expert teachers learn more the widest range of resistance as a thin wire has fewer electrons to carry the current than a thick wire therefore the resistance is higher resistance in a wire increases as: the length of the wire increases. I've got to do some coursework on the resistance of a wire and if the length of the wire affects the resistance i need to explain why the longer the wire the bigger the resistance is i know it is because of the amount of collisions, but could you help me in understanding what exactly happens during the collisions and how it affects the resistance.
