Resistance of a wire coursework - sample essay cause a big problem as the same wire was used for each set of results so it is known that the results for each wire . 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. Class practical investigating the changing resistance of a wire as it heats up apparatus and materials power supply, low voltage, dc eg 12 v, 4 a at least rheostat (10 - 20 ohms) rated at 5 a at least aluminium container (eg. Hello i recently posted a topic on this but i havent finished asking some more questions if you may please reply i'm doing a physics coursework on the resistance of a wire: im not sure which material to use to measure the length, either:.
The fact that, as the wire got shorter and therefore the resistance greater, i could not keep the wire from heating up 2 the wire i was using had a tendency to wind up, diminishing my precision and accuracy in measuring the length. An investigation into the resistance of a wire - gcse owlcation stem investigating-the-resistance-of-wire an investigation into the resistance of a wirefree gcse physics coursework essay. My results show me that once the readings on the ammeter and the voltage increase, so will the resistance, because of this we decided to increase the length of wire .
- 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. 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. What general pattern do these results resistance of a wire coursework results table become a smh member today join today and you can easily save your favourite . Preet kaur: physics report- resistance myp5 ib then there is likely to be more collisions in a longer wire more collisions results in more resistance4 figure 3 .
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. Resistance in a wire coursework in this investigation we are trying to look for resistance in a piece of wire, and how the length of a wire can increase or decrease the resistance. Wire resistance essay examples 13 total results an analyis of the resistance of a wire and the way it can be affected by certain factors. A-level results day 2018 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 . An investigation into the resistance of a wire free gcse physics coursework essay (which could potentially affect the results because the wire would get too hot .
Gcse physics coursework - resistance of a wire coursework the overall resistance of the two wires seems to differ considerably due to the strong correlation of the results, the explanation of this is unlikely to be the method used to obtain the results. Resistance of a wire coursework essay is defined as the resistance in the wire, use and measuring each value to a certain degree of accuracy for all results . Resistance of a wire coursework essay so is the resistance after looking at my results from the experiments, i believe that the results are satisfactory enough .
The type of wire will also give me a good range of results because i will be able to see if the difference in thickness of wire makes a difference and if the different type of wire makes a difference. Resistance wire method an investigation into the resistance of a wire gcse physics in nbsp resistance wire coursework results how the length of a wire affects its resistancein my physics coursework i am results: length nbsp. In the first experiments for length of wire we didn’t specify a length of time that we were going to measure resistance on the wire for, we just laid the wire on the other wire, however this would have heated the wire giving us less accurate results. 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).
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. 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 .
Introduction in this piece of coursework i aim to find the effects of length on a piece of nichrome wire resistance is a force which opposes the flow of an electrical current, this is why energy is needed to push the particles around. Record results 5 change the lengths of wire and do same steps 2 more times resistance of a wire coursework resistance of a wire task to investigate how the . The resistance of a wire is given by the equation: r = ρ x l/a where r is resistance, ρ (pronounced 'rho') is the resistivity of the wire, l is length and a is its cross-sectional area the gradient of each graph will give you the quantity ρ /a.
