Apr 12, 1. I will also control, using the power pack, how many volts pass through the wire. Physics Coursework Theory — Resistance of a Wire.
Planning Up to 8 marks are available for planning your practical investigation. Resistance of Wire Short 0? The resistance of a length of wire is calculated by measuring the current present in the circuit in series and the voltage across the wire in parallel.
Gcse Physics Coursework Resistance Wire Conclusion for resistance of a wire coursework with the wire being 10cm and 20cm long. I will then turn the power pack on and record what voltmeter and ammeter readings.
The free electrons are given energy and as a result move and collide with neighbouring free electrons. In addition, I will make sure I turn the power pack off after each reading.
We imagine a wire being a series of identical resistances connected in series, so it seems logical that resistance is proportional to length; we might ask the question behind our results Resistance of a wire coursework methodElectrical wire resistance chart — Resistance of a Wire Coursework.
Again, I will record the voltmeter and ammeter readings and turn off the power pack. Apparatus Ensuring Accuracy To ensure accuracy I will record the voltage and the current three times every 5cm and take the average reading.
This will reduce the chance of false readings and will cancel out any anomalous results. I could have considered using a new piece of wire each time in order to regulate the temperature more stringently.
Below is a table illustrating the effect of changing the variables see Table 2: In this piece of coursework, I have been finding out factors that affect the resistance of a wire.
All wires in a circuit offer some resistance to the flow of charge If we have a wire rated for AC V RMScan childhood vs. Conclusions Having performed the investigation, the following conclusions were drawn: Thanks to anyone for helping. Coursework Aim To find out how the length of a wire can affect resistance.
There are no anomalous results that I would consider to be far away from the line of best fit.
Adulthood this wire be used for DC application with the DC voltage not exceeding the peak value of. For example, gold has more free electrons than iron and, as a result, it is a better conductor. These collisions convert some of the energy that the free electrons are carrying into heat.
I will also ensure that the wire does not heat up too much by confirming that I do not set the voltage too high on the power pack and by maintaining the same the voltage for every reading.
