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.

I will make sure to site it and give you full credit! Thanks, this helped me with my investigation in Physics, I was really confused about it. I know you stated it was Nichrome, and cm long, but the SWG is not stated - Am using your data as secondary data and need to compare my investigation and yours. This is by far the beast source of information I could find for my coursework, you are awesome:.
Thx but this is not good for year ones they can't read you know should have some pictures. This had really helped me with my Year 9 work. I really appreciate the info you have logged into this. Once again, thank you! Other product and company names shown may be trademarks of their respective owners.

Introduction In this article I will investigate what affects the resistance of a wire. A wire's resistance depends on four main factors: Resistivity Length of the wire Cross-sectional area Temperature of the wire I will investigate how the length of the wire affects the resistance. Preliminary Investigation Below are my results from the preliminary experiment see Table 1.
Table 1: Preliminary Results. Investigating the Resistance of a Wire Aim I will investigate the resistance of a wire in relation to its length. Prediction I predict that the longer the wire, the larger the resistance. Apparatus The apparatus I will use in this experiment is as follows: 1 ammeter to measure current 1 voltmeter to measure voltage 5 x wires 2 crocodile clips Power pack cm nichrome wire Method First, I will collect the apparatus I need and set it up as shown in Diagram 1, below.
Diagram 1: Apparatus.
Ensuring Accuracy To ensure accuracy I will record the voltage and the current three times every 5cm and take the average reading. Variables There are different variables that can be changed in this experiment; these are the independent variable.
Table 2: Variables. Safety 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. Results Below is a table of my results Table 3. Table 3: Results. 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. Questions must be on-topic, written with proper grammar usage, and understandable to a wide audience. This stuff has greatly helped me to finish my physics assignment. Thanks a lot this has been a great help for me and my fellow classmates.

I used some of the data for my physics homework so thanks for that. Just remember to keep on munching chicken like me. Thank you so much for this as it helped a lot in my physics class. This was really helpful for my controlled assessment. Thanks, I needed a secondary data source for my controlled assessment. Sam: No worries. Lucy: Glad to hear it, Lucy.
Best of luck with your future tests and exams. Voted up : Must be of great help for those students who are doing physics. Sign In Join. This was because I could plot a graph and show the general trend. However, I think that unless I had physics equipment the results safety be distorted because the wire would eventually get very hot. I resistance my method could have been improved to produce results that were even more consistent. I could have considered using a new piece of wire each time in order to regulate the temperature more stringently. Using the same piece of wire throughout the safety meant its temperature rose slightly over time, which may have affected my results.
However, using new pieces coursework wire each time would have been too impractical and time-consuming in the context of this lesson. Overall, Visit web page think my method was physics to obtain reliable results. To support my prediction and conclusion, I could do further wires. For example, I could use different types of wire instead of using only nichrome. Here 39;s what of that wire afterwards. Can resistance help me out here?
