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. Home » gcse physics coursework resistance wire a+ r a-s'abonner à ce flux rss gcse physics coursework resistance wire click here gcse physics coursework resistance wire. How the length of a wire affects its resistance in 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 i will then repeat the experiment for wire lengths of 20cm, 40cm, 60cm, 80cm, 150cm, 200cm, 250cm and 300cm.
Physics coursework objective: my objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire the one i am investing is the length at constant temperature. Physics coursework objective: my objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire the one i am investing is the length at constant temperaturemy objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wirethe factor i chose was length. Investigating the effect of length on resistance is common but some students may wish to investigate the effect of the thickness of wire in either case, different wires should be made of the same material.
From this i know that the resistance of 20cm wire should be double the resistance of the 10cm wire and the 40cm wire double that of the 20cm wire, etc experiment 1 length amps volts resistance (+ 1cm) after obtaining my results from the experiments i plotted 3 graphs showing these and also another graph showing the average results. Resistance of a wire coursework is a part of physics curriculum while in school and college, students need to attend to various types of coursework depending on the subjects and course modules, students will write different coursework. 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. Resistance experiment coursework an investigation into the resistance of a wire gcse science – marked by i will be examining the resistance of a wire this experiment queries the relation between voltage and amps flowing through nbsp aim: the aim for this experiment is to check if the length of a wire resistance.
This experiment nbsp resistance of a wire length coursework research paper academic is a physics assignment which is rather complex and have most students seeking coursework help. Make sure the coils in the resistance wire don’t touch and short circuit because this will ruin the experiment and may heat up the wire and catch fire we will write a custom essay sample on resistance coursework specifically for you. 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. Resistance of a wire coursework - sample essay for example, gold has more free electrons than iron and, as a result, it is a better conductor the free electrons are given energy and as a result move and collide with neighbouring free electrons.
I am currently doing my physics coursework and i was just wondering if you could help me get a bit more scientific information on why things occured and happened the way they did basically i am studying how length affects the resistance of a wire and i have initially completed this project but i am just re-reading and adding in some information. - 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. Extended experimental investigation: electricity modify your experiment if necessary gather, record and process data from the measurement of the total resistance to give the resistance of the copper wire that was to be measured the alligator clips were clipped together, so that the resistance of the wires of the. Introduction in this piece of coursework, i have been set the task of investigating factors that affect the resistance of a wire there are many things that affect the resistance of a wire but i have only got the chance to do one of these.
To get the full marks for my gcse coursework how does length affect the resistance in a wire i need to provide an alternative experiment that i could perform if i were to redo the investigation i have already calculated resistance in circuit using ohm's law and predicted results using the r=ρl/a. Coursework aim to find out how the length of a wire can affect resistance factors affecting resistance temperature length of wire thickness type resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to. 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.
The resistance of a wire is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire (3) this means that when the than a 30 swg copper wire in the experiment a metal called constantan was used and the. Experiment: ohmic resistance and ohm 39s law – 1557 words bartleby of a wire affects its resistance in my physics coursework i am going to to help me plan my investigation i have completed a preliminary nbsp physics controlled assessment – ocr require candidates to: a particular idea, that of the resistance of wires of different thicknesses. The resistance of a piece of wire is 1 ohm if a current of 1 a flows through it when a voltage of 1 v is applied between its ends if you plot a graph of current through a piece of wire against the voltage applied you should get a result like the one shown in the diagram.
