In the conduction of this experiment i will be examining the resistance of a wire this experiment queries the relation between voltage and amps flowing through 5 different thicknesses of wires electricity is transported through the wire by electrons when a circuit is switched off and there is no electric current present the. 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 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. 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. 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. Summer research program for science teachers ghulam firdaus law and public service hs, manhattan august 2005 how to find out the unknown resistance of a wire through a series circuit background knowledge students should have already learned: the fundamental concepts of voltage, current, and resistance.
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. The problem statement, all variables and given/known data find the resistance of a 14 m length of copper wire with diameter of 510^-3 m 2 relevant equations r = p(l/a) where p = resistivity of copper, l = length, a = area 3 the attempt at a solution the resistivity of copper is (169 10^-8) radius is. 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.
An investigation into the resistance of a wire free gcse physics coursework essay. 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 variable changes in response (eg the resistance increases) the control variable.
