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. In this piece of coursework you have to take careful measurements, with particular attention to the quality of the measurement and any inferences you can is it to measure a particular quantity (eg young' modulus), to establish a mathematical relationship between two variables (eg resistance and temperature of wire),. 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. Tutorials, tips and advice on gcse physics coursework and exams for students, parents and teachers resistance & length two wires, same diameter, different lengths electrons moving through the short wire only feel resistance for a short time compared to the longer one this means its resistance is less think of 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 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. 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,. We got just given our coursework in college and i am utterly clueless on what to do for this i'm supposed to be investigating how changing the length of the wire in a circuit affects its resistance and then calculating the constant resistivity of that wire afterwards can anyone help me out here how do you set.
Some useful worksheets for the old resistance in a wire coursework. Resistance there is a resistance to the flow of an electric current through most conductors the resistance in a wire increases as: the length of the wire increases the thickness of the wire decreases.
Physics gcse coursework: factors affecting the resistance of a wire ali hlaiyil introduction: before starting my coursework i have decided to choose 2 factors that will affect the resistance of a wire i will do this by going through all of the factors that affect the resistance of a wire and how i would measure each factor to find. 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. 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 what is resistance electricity is conducted through a conductor, in this case wire, by means of free electrons the number of. 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.
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.
