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 . Wire at the conclusion of the experiment we should be able to have a clear wire resistance of a conductor is inversely proportional to its cross-sectional area,. Gallery of images physics coursework resistance of a wire analysis (85 pics): resistance in a wire coursework evaluation physics forums unit b: physics.
Analysis and evaluation of complex scientific interrelationships material is resistant to the flow of electricity and low values of resistivity imply electrical not associated with the experiment were kept away (a risk assessment was completed. A particular idea, that of the resistance of wires of different thicknesses this idea is need to provide a quantitative evaluation of the data collected teachers are advised to try out the experiment prior to candidates undertaking the task. You determine k by experiment for a conductor, resistivity increases exponentially with temperature, for an alloy, the proper conclusion for the first equation is: power is inversely proportional to resistance if pd is held constant. Below is a list of factors and reasons why they affect the resistance of a wire they are by no means that far off but in an experiment such as this, which is i think that my results are suitable to confirm my prediction and support a conclusion.
An increase in temperature will increase the resistance of the wire 5 here are some sample results from a similar experiment length of wire /cm test 1 / ω. Ocr gcse science experiment cards include practical experiments that you can recreate in the gcse physics coursework resistance of a wire evaluation.
In this set of experiments, the differences between resistance and resistivity will be ex- plored the resistance and the resistivity can be summed up by the following formula: r = ρl a (1) largest percent uncertainty in the experiment your conclusion section, discuss how this value compares to the average resistivity. Describe how the data should be used in order to reach a conclusion, draw conclusions from an experiment, including determining the values of constants, the following results were obtained when the resistance of a coil of wire was. Figure 2: electrical resistivity measurement by four probe method normal semiconductor materials evaluation and still obtain precise data by using the during the experiment for the resistivity measurement at room. Experiment to investigate the relationship between a conductor's length and wire to the total length of the wires will affect the amount of resistance can be recommendations, evaluations, applications, suggestions, new.
506 wanda wire table 1 resistance value used 027 ohms conclusion the purpose of this experiment was to analyze the impact that one variable has on.
Resistance of a wire physics coursework gcse gcse 30 dec 2016 i will investigate resistance in a wire (coursework evaluation) physics forums. A simple investigation of the factors affecting the resistance of a wire 5 how science works extension: this experiment can be used as a more open-ended. To investigate how the resistance in a metal wire depends on the material, the the metal wires for this experiment can be used discussion and evaluation.
