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 current is the rate. Controlled assessment for gcse gateway science, all of which are available from the website 4 wwwgcse-sciencecom gcse gateway science candidate style answers physics candidate a the resistance of a wire is directly proportional to the length of the wire and inversely. The two physics ones were on 'the resistance of a wire' and the other one for physics is to do with the danger of mobile phones more simple the task that i was expecting that its hard to think about things to write, so i think i didnt do well in my biology controlled assessment in comparison to the other two. Carry out an investigation of the relationship between the length of a metallic conductor (eg nichrome wire) and its resistance introduction background research outlined and referenced firstly i researched this topic in my science book i found relevant information in my book about resistance, such as the fact that. Myphysicsorguk/docs/ks4cainvimpgdpdf wwwmyphysicsorguk improving your investigation mark and grade example marks to get each grade sa sb c a ea eb ra rb grade mark needed / 64 total of example marks hypothesis method + ra collecting analysing (graph) evaluating procedures evaluating. We know from the book of ordinary level physics by af abbott that the resistance of a conductor is affected by several factors: surface area: thick wires may investigating how the length of a wire affects its resistance essay - investigating how the length of a wire affects its resistance planning: risk assessment: i.
Before starting my coursework i have decided to choose a factor that will affect the resistance of a wire i shall do this by evaluation as mentioned previously, the biggest downfall of the investigation was the apparent mistakes when choosing the wire, in that they would appear to be of differing diameters this did not, in. 2016年5月11日 free essay on hostel life computer sales assistant resume gcse physics coursework resistance of a wire evaluation horacejem 2017年2月3日 at 8:46 pm gcse triple science coursework business plan program mac funding coordinator resume horacejem 2017年2月3日 at 9:11 pm functional resume it. Three sections: biology, chemistry and physics, all questions to be answered coursework b mark the sec nominated investigations according to the agreed criteria enter the marks for each section in the coursework b grid on the cover page of the coursework booklet or resistance of wire / metal of wire / volume.
Circuit to collect data on current and voltage, and calculating the resistance of a wire (p4c) teachers may wish to refer to: http://wwwpracticalphysicsorg/go/ experiment_276html candidates should be made aware of the: • health and safety issues • need to provide a quantitative evaluation of the data collected • sources of. An in investigation into the resistance of a wire aim: to investigate the factors affecting resistance there are four main factors which affects the resistance and they are: the material the cross-sectional area (thickness) the length the temperature but in this investigation i am only going to investigate in the factors length. Assessment is entirely by coursework and continuous assessment — there is no written examination attendance a part of a circuit whose resistance is infinite (a perfect insulator, or a badly made 'dry' solder length of wire is pulled it stretches, and that for small forces (or loads, since the force is often.
6 | physics 2007 sample assessment instrument and indicative responses comments hypothesis if the length of a wire is increased then its resistance will increase if its cross-sectional area and temperature remains constant if the cross -sectional area increases then the resistance of a conductor will decrease if its length. Physics coursework title 2017 using conductors made of children's play ( modelling) dough, investigate quantitatively the effect on resistance, calculated from measurements of voltage across and current through the conductors, of changing the conductor length and obtain data to establish whether dough colour has an.
The classic physics experiment this was designed as an intro for an isa but could be used for this practical in any syllabuss it includes model results, info on variables , anomalous data and graphs. Physics gcse coursework: before starting my coursework i have decided to choose 2 factors that will affect the resistance of a wire evaluation the experiment went fairly well, with good results and graphs obtained all round we didn't encounter any problems, and as far as seen so far there were no major problems. Key factors reasons given for controlling how i controlled the variable the current must remain the same if the current isn't the same the results will be affected and they are most likely to decrease if the current is increased and if the current differs for each of set of results it wouldn't be a fair test we also need to keep the.
This blog post offers 16 detailed ideas for the ib physics ia - aimed to help both ib teachers and students through the ib internal assessment using thick copper wires of low resistance, to keep the resistance in wires (and resulting heat loss) to a minimum using laminated layers in the iron core to reduce the formation of. Whatever, more information is needed to answer the question edit: if it is to do with the increase of resistance with temperature we should be told that the wires are identical the graphs should not be straight lines if it is to do with the increase in temperature with power generated we should be told that.
