A simple investigation of the factors affecting the resistance of a wire investigating the resistance of wires activity. The fact that, as the wire got shorter and therefore the resistance greater, i could not keep the wire from heating up 2 the wire i was using had a tendency to wind up, diminishing my precision and accuracy in measuring the length. Theory suggests that the resistance of a wire is found with this formula: r= l/a r = resistance = resistivity of wire l = length of wire a = cross-sectional area i will now perform an investigation to confirm the legitimacy of this formula and confirm a value for in a nichrome wire. Essays-year 10 coursework- resistance of a wire. Our recommended wire gauge calculator helps determine the correct wire gauge for your application based upon the input parameters of length, current, voltage and more the recommend gauge is the result of applying abyc standards factors, allowable voltage drop and any additional derating factors.
- 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. Resistance is directly proportional to the length of the wire, and inversely proportional to the cross sectional area of the wire r = pl/a, where r is resistance, p is the material's resistance in ohms, l is the length, and a is the cross sectional area in m^2as a wire gets longer its resistance increases, and as it gets thinner its. R = resistance l = length of wire if a wire is stretched to double its length then folded in half, what would be the resistance of the wire. Of straight wire of length l and cross-sectional area a, resistance of the battery and the connecting wires, upon returning to a the potential.
Experimentally, the dependence upon these properties is a straightforward one for a wide range of conditions, and the resistance of a wire can be expressed as resistance = resistivity x length / area. Hello i recently posted a topic on this but i havent finished asking some more questions if you may please reply i'm doing a physics coursework on the resistance of a wire: im not sure which material to use to measure the length, either. Preet kaur: physics report- resistance myp5 ib uploaded by preet kaur the resistance and the length of the wire is directly proportional to each other. 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.
Resistance in a wire coursework in this investigation we are trying to look for resistance in a piece of wire, and how the length of a wire can increase or decrease the resistance. Free college essay investigating the resistance of wire investigating the resistance of a wire length of the wire gcse physics coursework - resistance. I think as you increase the length of the wire, you also increase the amount of resistance the current is the flow of electrons the current is dependent on the amount of voltage, which is applied.
