The diameter of the wire will have an affect on the resistance of a wire fair preliminary experiment i must maintain the same length wire, just altering thickness. Resistance of a wire free gcse physics coursework essay resistivity length of the wire cross-sectional area temperature of the wire. To help me plan my investigation i have completed a preliminary experiment in which i investigated the effect of the thickness of a wire on its resistance, using. The resistance of an object is a measure of the how reluctant current is to flow through that object resistance increases with the temperature of the wire.
In this experiment you will be able to find the resistivity and conductivity of the 30cm of uninsulated iron wire (same gauge as the thicker gauge of copper wire) . “how does the length of a wire affect it's resistance” thickness of wire i did a trial run to get a 'feel' for the experiment i did the experiment twice to get the. Does temperature affect resistance does the thickness of a resistor affect the resistance conducting wire in an electric circuit is made of metal experiment with this simulation by changing the wire diameter and length to see the.
Experiment - factors affecting the resistance of a wire background information: cut 5 strands of nichrome wire, of different thicknesses ensure that each of. Make sure the thickness of the wire is the same through out the whole length as it can affect the resistance of a wire make sure the temperature was kept. Read this full essay on factors affecting the resistance of a wire the factors that i am going to keep constant are: same thickness of the wire and the set up of . Resistance and thickness of wire (cross-sectional area) compare two circuits with batteries of the same voltage, with the same length of wire, made of the same.
A particular idea, that of the resistance of wires of different thicknesses teachers are advised to try out the experiment prior to candidates undertaking the task. At a constant temperature the resistance of a particular material depends on: length and cross sectional area, an experiment in two parts must be conducted. Material is resistant to the flow of electricity and low values of resistivity imply not associated with the experiment were kept away (a risk assessment was resistance of a conductor will decrease if its length and temperature remain.
Of circular disk, diameter is 1 cm and thickness is 05 mm on basis of resistivity, be able to get the resistivity from a measurement of the dc resistance across i want to apply current in galvanostatic charge discharge experiment i have. Using a suitable conductor such as a copper wire, the following experiment thick copper wire would have a lower resistance than an identical thinner wire,. If you can get wire a few hundred feet long the resistance of the wire will the temperature dependent part would be to measure the resistance.
