Physics sec 24 syllabus available in september (paper i and paper iib only) paper 1 (2 hrs) + paper 2 (2 hrs) + laboratory reports introduction investigate the factors affecting resistance in a wire filament of lighting bulb, heating elements, suitable wires for different appliances 512 be familiar with the circuit. Oct 1, 2011 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 method gave good results because the percentage differences were small and all the. The resistance of an object is a measure of the how reluctant current is to flow through that object it is given the symbol r and has the unit w (which is a greek letter omega and pronounced 'ohm') current only flows through a component of a circuit if a potential difference (voltage) is put across it the bigger the potential. The problem statement, all variables and given/known data the question asks for resistance r of a disk with radius r and fixed width w, whose cross sectional area is variable is the curved area divided into two with conductor deposited along the entire curved surface except for two thin cracks, or. In this post, i'm going to provide 16 actionable ideas for ib physics ia, including advice on which variables might be good to investigate 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 eddy. First before starting my coursework i have decided to choose 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 would be the most effective and easiest factor to measure below is a list of.
To the people taking their gcses in 2017, do you have all of the coursework titles i know: biology - factors that affect breathing rate physics - resistance in wires chemistry - if anyone knows the chemistry title for ocr 21st century a science then please say, because our school is going through it so. 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. This can be attributed to the lower amount of resistance that is present in the wider pipe (the physics classroom,2016) in the same manner, the wider the wire , the less resistance that there will be to the flow of electric charge when all other variables are the same, charge will flow at higher rates through. Gcse physics specimen assessment materials for first teaching from september 2011 for first assessment from summer 2012 for first award in summer 2013 it is believed that the variables h and c are related by the equation (d) the resistance of a piece of wire depends on its length and its cross-sectional area.
Physics coursework - resistance plan what affects the resistance of a piece of wire there are many variables in this investigation the resistance of the wire could depend on: the voltage from the power pack the voltmeter the ammeter the length of the wire the piece of wire used ie the material it is made. Typical setup to measure the resistivity of a wire note:that the battery/cell and rheostat (variable resistor) can be replaced by a variable power supply equipment 1m of constantan wire of nominal diameters 027 and 056 mm, 1m of nichrome wire of nominal diameters 027 and 056 mm constant.
30 materials 1 40 method 2 50 results 3 - 51 qualitative observations 3 - 52 data 3-4 60 discussion 5 70 conclusion 6 80 bibliography 7 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. The resistance of a conductor is a measure of how easy or hard it is for a current to flow through it a wire will warm up when a current flows through it an increase in temperature will increase the resistance of the wire so measurements have to be taken quickly before the wire has a chance to warm up. An investigation into the resistance of a wire - gcse physics coursework updated on resistivity length of the wire cross-sectional area temperature of the wire i will investigate how the the variables i will control will be the type of wire (resistivity) and the cross-sectional area of the wire i will also.
Gcse physics resistance & length gcse resistance the physics classroombbc gcse bitesize resistance i am going to give a different explanation why is it that when the length of wire increases(acting as variable resistor) chance them being blocked or whatever) higher resistance i would think would,. Alternative method with strings or wires and suitable tranducer (eg vibrator) for a level physics required practical no 1 investigation into the variation diameter of the wire(s) other details of experiment fully specified teacher suggests outline method to determine resistivity by measuring resistance of wire but does not. Physics b unit b753: physics controlled assessment controlled assessment teacher guidance instructions to teachers this document contains: circuit to collect data on current and voltage, and calculating the resistance of a wire (p4c) teachers a variable resistor in series may help to control the current.
Physics a-level coursework studying how the resistance of a thermistor varies with temperature valid for as level physics by adan_farpón in types presentations and physics alevel variables: in my experiment, i will be measuring how the resistance of the wire changes, so resistance is my dependant variable. Variables these are the items that are being studied in a scientific investigation in physics, the variables are almost always quantitative, ie have a value that is a number categoric variables are those the independent variable is the one that we change (eg by changing the length of resistance wire) the dependent.
