As others have noted, the big issue is getting the resistance of the wire into the range where your multimeter can essay writer program measure it accurately. I used some of the data for my physics homework so thanks for that. Search Browse Essays; Join now! I will stand up during the investigation to ensure that I do not injure myself if something breaks. Below is a table illustrating the effect of changing the variables see Table Resistance in a Constantan Wire. Retrieved from ” https:
I predict that the longer the wire, the larger the resistance.
In this experiment I predict that the longer the length of wire the greater the resistance. The other variables included in this experiment are temperature, thickness of wire and density of wire. I could have considered using a new piece of wire each time in order to regulate the temperature more stringently.
The resistivity of Constantan Research Paper Example :
Discussion The resistivity of the two wires should have given the same result as they were both made from constantan, however the wires gave two different results. These results show that as the length of the wire increases, the resistance increases, as well. It was noted that all the experimenters present found they calculated a lower value for the 30 S. A wire’s resistance depends on four main factors: Postage and packing are also very reasonable – Their details are as follows: For example, when the length of the wire is 20cm the resistance is 3.
Do this by taking at least 10 readings at nbsp; Lab Report 4 — — Course Hero: Visualizando 1 post de 1 do total. Strain spanish essay writer gauge sensitivity is calibrated with FG.

Measure the diameter of each wire using a micrometer and then measure their lengths in metres.
Thanks a lot this has been a great help for me and my fellow classmates. Therefore if you multiply the gradient by the cross-sectional area, this will give you the resistivity of the wire. Look in the table for material resistivity for commonly used materials. In this experiment we will be investigating how changing the length of a piece of Constantan constantaj will affect the resistance. I found that the resistance increased as the resistancw of the wire decreased, however, when I did the test with the copper nbsp; Measurement of the resistivity of the material of a wire of the leads when the crocodile clips are connected together.
Measuring the voltage and the current on four constantan wires with different cross-sectional areas. To ensure accuracy, I have taken three readings each of volts and current. Using the coursewok alter the number of volts running through the circuit until approximately 3 amps is reached.
Thanks, I needed a secondary data source for my controlled assessment. A resistance wire AB of uniform cross section, usually one meter in length, is mounted on a board with auxiliary components neces nbsp; A-level Physics Test Unit 03T — P14 ISA June — AQA cobstantan performed to investigate how the resistance of a length of constantan wire varies with the diameter of the wire.

The results will help nbsp; Investigating the resistance of wires — Practical Physics of a wire. The resistivity of Constantan. Resistance Constantan Wire Coursework – chigo. Search Browse Essays; Join now! Also, the apparatus I had use of at school would not be suitable if I were to keep increasing the length of the wire; e.
To ensure accuracy I will record the voltage and the current three times every 5cm and take the average reading. Some articles have YouTube videos embedded in them.
I will investigate how the length of the wire affects the resistance. No data is shared with Facebook unless you engage with this feature.
