We may use remarketing pixels from advertising networks such as google adwords, bing ads, and facebook in order to advertise the hubpages service to people that have visited our sites. 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 is used to provide data on traffic to our website, all personally identifyable data is anonymized. For example, when the length of the wire is 20cm the resistance is 3.

This confirms the first part of my prediction that the longer the wire the larger the resistance. For example, i could use different types of wire instead of using only nichrome. No data is shared unless you engage with this feature. . In addition, i will make sure i turn the power pack off after each reading.
Furthermore, if you double the length of the wire, the resistance is roughly doubled. I have done a preliminary experiment to help me decide the best way to do my investigation. I will stand up during the investigation to ensure that i do not injure myself if something breaks. 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 Resistance In A Wire Coursework Introduction Buy now
Resistance is a measure of how hard it is to move the electrons through the wire. These collisions slow down the flow of electrons causing resistance. I could not increase the length to more than 150cm because of safety concerns as well as space constraints. 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. There are no anomalous results that i would consider to be far away from the line of best fit.
Results 2 length of wire (cm) current (a) voltage (v) resistance (?) 5 1. This is used to provide traffic data and reports to the authors of articles on the hubpages service Buy Resistance In A Wire Coursework Introduction at a discount
However, using new pieces of wire each time would have been too impractical and time-consuming in the context of this lesson. Below is a table illustrating the effect of changing the variables (see table 2) 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. Therefore, ohms law says the more resistance means more energy used to pass through the wire. Thanks, this helped me with my investigation in physics, i was really confused about it.

Comscore is a media measurement and analytics company providing marketing data and analytics to enterprises, media and advertising agencies, and publishers. Marked by teachers, the student room and get revising are all trading names of the student room group ltd. I will also control, using the power pack, how many volts pass through the wire. If the particles in the material are tightly packed together, the electrons will have more collisions and therefore more resistance. If this is correct, the graph should show a positive correlation.
I will repeat this method every 5cm until i get up to 100cm, taking three readings from both the voltmeter and ammeter each time to ensure accuracy Buy Resistance In A Wire Coursework Introduction Online at a discount
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. No data is shared with facebook unless you engage with this feature. Equipment wires batterypower pack voltmeter ammeter crocodile clips ruler resistance wire method 1. Overall, i think my method was sufficient to obtain reliable results. I found that the apparatus i used was suitable, but i think that i could possibly increase the number of data points to generate more reliable results, perhaps by increasing the length of the wire by 5cm each time, instead of by 10cm.
A wires resistance depends on four main factors i will investigate how the length of the wire affects the resistance Resistance In A Wire Coursework Introduction For Sale
I predict that the longer the wire, the larger the resistance. A resistor has the resistance of one ohm if a voltage of one volt is requires to push the current of one amp through it. Next, i will set the power pack on the lowest voltage possible to ensure that the current passing through the circuit isnt too high (which could potentially affect the results because the wire would get too hot). Wire length if the length of the wire is increased then the resistance will also increase as the electrons will have a longer distance to travel and so more collisions will occur. There are different variables that can be changed in this experiment these are the independent variable.

I will also ensure that there is a clear indication that the power is isolated by means of a switch and an l. Equipment wires batterypower pack voltmeter ammeter crocodile clips ruler resistance wire method 1. Furthermore, the resistance of a wire is directly proportional to the length and inversely proportional to the area, so doubling the length of a wire should increase the resistance by a factor of two. The variables i will control will be the type of wire (resistivity) and the cross-sectional area of the wire. What was the swg (standard wire gauge) or diameter of your wire? I know you stated it was nichrome, and 100 cm long, but the swg is not stated - am using your data as secondary data and need to compare my investigation and yours Sale Resistance In A Wire Coursework Introduction
