If yes, then that would make sense, as I did a quick test and using a halved p. I did repeat readings to get an average but this is just one reading as an example. Thanks, this helped me with my investigation in Physics, I was really confused about it. I have done a preliminary experiment to help me decide the best way to do my investigation. This is used to provide data on traffic to our website, all personally identifyable data is anonymized. Ensuring Accuracy To ensure accuracy I will record the voltage and the current three times every 5cm and take the average reading. Menu How checksum works write all steps of the scientific method How to write an outline for a documentary script Guided by voices essay.
Thread starter emikkime Start date Mar 5, Varici esofago -gastriche in continuazione con le varici esofagee e si estendono. There are no anomalous results that I would consider to be far away from the line of best fit. I know this is a lot to read, and I’m asking a lot for help, but please, can you find what I’ve done wrong, or anything? Prediction I predict that the longer the wire, the larger the resistance. However, using new pieces of wire each time would have been too impractical and time-consuming in the context of this lesson.
The metal is full of “free” electrons that do not stick to any particular atom; rather, they fill the space between the atoms. Members and 1 Guest are viewing this topic. Overall, my results are very consistent with my phyics.
Dissertation gilles aillaud Essays on ethics in social work Top admission essay editor website for masters Formal english essay example Best report writing site for masters Constantan is a Nickel-Copper based alloy wire that has a high resistivity and is mainly used for thermocouples and electrical resistance heating.
Join them; it as physics coursework resistivity only takes a minute: Discussion Overall, my results are very consistent with my predictions.
Applied Science AQA/Resistivity Portfolio – Wikibooks, open books for an open world
The change in resistivity as a result of temperature change is described by the temperature coefficient. This is used to provide traffic data and reports to the authors of articles on the HubPages Service.
I will stand up during the investigation to ensure that I do not injure myself if something breaks. 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. Finally dividing by the length 1metrewhich leaves the same answer.
This is because the free electrons in the wire bump into more atoms, thereby making it harder for electricity to flow. Resistivity of a wire – AS coursework.
I have taken three reading and have worked out the average, shown in red. 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. This paper presents the electrical resistivity component of an undergraduate geophysics course resistivity coursework Radford University. I did repeat readings to get an average but this is just one reading as an example.

No data is shared with Paypal unless you engage with this feature. This was because I could plot a graph and show the general trend. What is electrical resistivity? Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics.

I will ensure experimental safety by confirming that all the wires are connected properly and that none of the insulation on the wires is worn. This will reduce the chance of false readings and will cancel out any anomalous results.
Just remember to keep on munching chicken like me. I used some of the data for my physics homework so thanks for that. Note the voltage and ensure the scale of volts used does not exceed this as the wire will get too hot. Memories of Students, Friends as physics coursework resistivity and Colleagues ” “No man ….
