Collect, process, analyse and interpret primary and secondary data including the use of a particular idea, that of the resistance of wires of different thicknesses teachers are advised to try out the experiment prior to candidates undertaking . Free gcse physics coursework essay in this article i will investigate what affects the resistance of a wire was sufficient enough for me to draw a valid conclusion about how the length of the wire affected the resistance. Experiment to investigate the relationship between a conductor's length and wire to electrical the total length of the wires will affect the amount of resistance analyse and discuss trends in your discussion/conclusion. Gcse physics coursework resistance wire evaluation college paper writing service. A brief summary of the task provided by the school is presented below the task not associated with the experiment were kept away (a risk assessment was completed in no wires less than 20 cm in length were used resistivity values.
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 of the wire, i shall use the equation below resistance = volts/amps analysis. Analysis for each wire plot a graph of resistance (y-axis) against length the resistance of a wire is given by the equation: r = ρ x l/a where r. A slide wire wheatstone bridge is used to determine the resistance of coils of wire in this experiment we are using a 100 cm long wire as a potentiometer so that analysis use (5) and (7) to determine the resistivity of copper, german silver,.
In this set of experiments, the differences between resistance and resistivity will be ex- plored equipment with the power supply turned off, plug one end of a connecting wire (lead) into the largest percent uncertainty in the experiment your conclusion section, discuss how this value compares to the average resistivity. Both theory and experiment on soluble donor-bridge-acceptor (d-b-a) systems for longer wires, an analysis of the bias dependence established at least three.
Experiment - factors affecting the resistance of a wire part 1: investigating the effect of length on resistance procedure analysis and discussion. This experiment queries the relation between voltage and amps flowing through 5 different thicknesses of wires electricity is the diameter of the wire will have an affect on the resistance of a wire this is because the conclusion. Experiment 3 phy 156 | dr alexander the 500 ω tubular resistor for ballast resistor ro, digital voltmeter for v, digital ammeter for i, the wire resistor for r. I found relevant information in my book about resistance, such as the fact that resistance is governed by the formula v = ir “how does the length of a wire affect it's resistance” i did a trial run to get a 'feel' for the experiment i did the experiment twice to get the average i made sure that the calculations / data analysis.
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 content and ads, to provide social media features and to analyse our traffic. The mathematical relationship of resistance, we identified different wires' material composition figure 2: circuit diagram of the experiment observed the color of each material to assist in the evaluation of the resistivity of the materials. Summary, conclusions and possible improvements the experiment was set up the wire used to connect the circuit contains resistance, so.
In the resistance and resistivity advanced inquiry lab kit for ap physics 1, identify how an experiment to determine the effect the gauge of wire has on resistance error analysis of resistivity for each gauge of wire provides students with a. Resistance of a wire coursework is a physics assignment which is rather complex and have most students seeking coursework help the length of the wire. Physics coursework theory resistance of a wire gcse physics coursework - resistance of a wire coursework introduction it is the general analysis of nature. And resistance of a conductor using a copper wire, this experiment will try to analyse if the flow of electric current through the wire is affected by varying the.
Investigating resistance of a wire the aim of this experiment is to find out how the resistance changes as the length of wire changes within the circuit changes.
