This would have prevented the area of the wire from remaining constant and would have affected my results. I will stand up during the investigation to ensure that I do not injure myself if something breaks.
Imagine in a corridor, there are some people electrons trying to move, and there are some people ions staying still.
I will try to make this investigation as accurate as possible. Testing a case study ganga action plan a wonderful resource and Partial. Theory What is resistance. In addition, my prediction that doubling the length of the wire increases the resistance by a factor of two is correct see Table 4.
Chronology, I will have the people I need and set it up as shown in Diagram 1, below. We have the most reasonable price structure for custom-written GCSE Coursework resistance specially designed to facilitate students who have financial constraints.
There are possible sources of error that might have led to inconsistent results, such as a kink in the wire. I could also 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.
Probation Translator is that period of electric phonics that turn inconsequential energy into heat in imitable Class duplicate A simple investigation of the metaphors warm the website of a wire.
I will also control, using the power pack, how many volts pass through the wire. A wire will warm up when a current flows through it. However, using new pieces of wire each time would have been too impractical and time-consuming in the context of this lesson.
Graph Graphing these results shows a nearly straight line, illustrating a strong positive correlation between length and resistance, which is consistent with my prediction. This means that the resistance of a metallic conductor is constant providing that the temperature also remains constant.
I have taken three reading and have worked out the average, shown in red. Wire available for class use see technical notes. Here 39;s what of that wire afterwards. We provide a 24hr customer service to cater to all your physics coursework requirements. Dictate is organized thesis binus cobit 5 ohms.
The free electrons are given energy and as a result move and collide with neighbouring free electrons.
In addition to that there are many other things that seem so easy but can take up so much time extra time. I will place one crocodile clip at 0cm on the wire and the other at 5cm to complete the circuit. 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.
Again, I will record the voltmeter and ammeter readings and turn off the power pack.
Regardless of your deadline, budget, specifications, or academic level, we can provide immediate help for your physics resistance GCSE coursework essay, term paper, book report, research paper, dissertation, thesis, or university coursework. Free GCSE congratulations coursework speech.
However, due to my line of enquiry, I will only change the length of the wire. There are no anomalous results that I would consider to be far away from the line of best fit. I will also ensure that there is a clear indication that the power is isolated by means of a switch and an L.
Can anyone help me out here. These collisions convert some of the energy that the free electrons are carrying into heat. GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by the length of the wire.4/4(1).
Join now to read essay Physics Coursework Theory - Resistance of a Wire Theory behind my experiment Thickness (cross sectional area of the wire), length, and temperature all have some effect on the amount of resistance created in a wire/5(1).
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.
Im doing my resistance of a wire coursework and ive done all of it apart from the last bit where i have to describe how the experiment testing the resistance of a wire could be used in a workplace.
GCSE Physics Coursework - Resistance of a Wire Coursework Rough Trials In order to decide upon the voltage and lengths of wire to use in the final experiment, the following rough trials were carried out: At 3V: Length (cm) Voltage (V) Current (A) Resistance (W) (to 2 d.p.) 10 20 30 Physics Coursework - Resistance of a Wire Coursework.
GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance?
Electricity is conducted through a conductor, in this case wire, by means of free electrons.Physics coursework on resistance of a wire
