Gcse coursework resistance

The number of free electrons depends on the material and more free electrons means a better conductor, i. For example, gold has more free electrons than iron and, as a result, it is a better conductor. I will then turn the power pack on and record what voltmeter and ammeter readings.

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. The variables I will control will be the type of wire resistivity and the cross-sectional area of the wire.

Electricity is conducted through a conductor, in this case wire, by means of free electrons.

In addition to that there are many other things that seem so easy but can take up so much time extra time. These measurements are then applied to this formula: Resistance is the result of energy loss as heat. There are a few data points that are farther away from the line of best fit than the others, but they are still consistent with the general trend.

It will appear to be very helpful for future work, as Gcse coursework resistance will show you the direction of your physics coursework. We have the most reasonable price structure for custom-written GCSE Coursework resistance specially designed to facilitate students who have financial constraints.

This would have prevented the area of the wire from remaining constant and would have affected my results. However, using new pieces of wire each time would have been too impractical and time-consuming in the context of this lesson.

I will switch off the power pack, move the crocodile clip that was at 5cm up to 10cm, and switch on the power pack. 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.

Yes we can do all your physics coursework no matter what the topic is or how unique your research requirements may be like our professionals will handle all those complicated and mind boggling assignments for you. Among other things you will have to create an outline for your coursework.

An Investigation Into the Resistance of a Wire - GCSE Physics Coursework

However, I think that unless I had specialist equipment the results would be distorted because the wire would eventually get very hot. It seems to Gcse coursework resistance quite an easy task, but it is much more difficult when you have to do it within a limited period of time.

I could Gcse coursework resistance consider using different cross-sectional areas of wires or even change the temperature of the wires deliberately and see how manipulating these variables affect the resistance of the wire. Most of the data points were on, or very close to, the line of best fit.

How is it measured? I think that the range of my results was sufficient enough for me to draw a valid conclusion about how the length of the wire affected the resistance. You will have not only to create the parts and sections of your GCSE coursework resistance of a wire and or Resistance of a wire courseworkbut also to describe each part with the help of some key words.

To support my prediction and conclusion, I could do further experiments. These collisions convert some of the energy that the free electrons are carrying into heat.

This confirms the first part of my prediction: Graph Graphing these results shows a nearly straight line, illustrating a strong positive correlation between length and resistance, which is consistent with my prediction.

Discussion Overall, my results are very consistent with my predictions. This was because I could plot a graph and show the general trend. I could have considered using a new piece of wire each time in order to regulate the temperature more stringently.

This will reduce the chance of false readings and will cancel out any anomalous results. I will place one crocodile clip at 0cm on the wire and the other at 5cm to complete the circuit.

In addition, my prediction that doubling the length of the wire increases the resistance by a factor of two is correct see Table 4.Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance.

Prediction (Hypothesis): I predict that the longer the wire the higher the resistance, and the shorter the wire the lower the resistance.
