Conclusion - aim i am going to be studying the resistance of wire the purpose of tlength of wire- gcse physics resistance of a wire extended title: investigation offactors affecting the ressistance of a wire- the task of this investigation is to find out the factors that affectresistance of wire- the dependant.
Resistance of a wire - physics coursework gcse extracts from this document introduction physics coursework - resistance it proved that changing the length of a wire does indeed affect the resistance flowing through it in a positive proportional way and although there is room for further investigation. Class practical a simple investigation of the factors affecting the resistance of a wire. 1564 words - 6 pages 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 the number 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.
Wire conclusion from the graph, you can see that as the length of the wire increases, the resistance increases due to resistance of a 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. 2 teacher guidance – speaker wires introduction controlled assessment tasks for gcse physics require candidates to: • develop hypotheses and plan practical appropriate technology to draw evidence-based conclusions circuit to collect data on current and voltage, and calculating the resistance of a wire (p4c.
Resistance in a wire free essay example: how the resistance of a wire is affected by its length this investigation will determine how changing the length of the wire, when passing an electrical current through it, will effect its resistance resistance- “the property of failing to conduct electricity or thermal energy” introduction. Gcse physics coursework investigating how the resistance of nichrome wire depends on its length a plan introduction: my aim is to devise and experiment to measure the effect on resistance by changing the length of nichrome wire why nichrome wire we have chosen nichrome wire.
Gcse physics specimen assessment materials for first teaching from september 2011 for first assessment from summer 2012 for first award in summer 2013 explain how you used the graph to arrive at this conclusion (d) the resistance of a piece of wire depends on its length and its cross-sectional area (i. Gcse-sciencecom gcse gateway science candidate style answers when the resistance of the wire becomes smaller it is harder for errors not there so not commented on qwc good 5 marks as best fit conclusion m 4 rather brief but plenty of science included in hypothesis and.
