### Resistance In A Wire Coursework Introduction

You are incorrect about the doubling the length of wire the resistance increases by a factor of two. . Similarly, the shorter the wire, the smaller the resistance because there will be fewer atoms for the electrons to bump into, thereby easing the flow of electricity.

Using the same piece of wire throughout the experiment meant its temperature rose slightly over time, which may have affected my results.

I have taken three reading and have worked out the average, shown in red. The electrons carrying the charge are trying to move through the wire, but the wire is full of atoms that keep colliding in the way and making the electrons use more energy. No data is shared unless you engage with this feature.

I really appreciate the info you have logged into this. Javascript software libraries such as jquery are loaded at endpoints on the googleapis. I could not increase the length to more than 150cm because of safety concerns as well as space constraints.

The metal is full of free electrons that do not stick to any particular atom rather, they fill the space between the atoms. 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. This was because i could plot a graph and show the general trend.

First, i will collect the apparatus i need and set it up as shown in diagram 1, below. I think my method could have been improved to produce results that were even more consistent. Resistance is a measure of how much energy is needed to push the current through something. Overall, i think my method was sufficient to obtain reliable results. 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.

• ### Physics coursework resistance of a wire conclusion

To support my prediction and conclusion, i could do further experiments. There are a few data points that are farther away from the line of best fit than the others, but they are still consistent with the general trend. Table 3 shows that as the length of the wire increases, the resistance increases, as well. Averages for each wire were then calculated to give these results, which were then graphed length (cm) equipment i will need 1 electrical wires 2 a power pack 3 an ammeter connected in series 4 a voltmeter connected in parallel 5 a wire attached to a meter stick to measure the length accurately 6 a power supply (a socket) if the material has a high number of atoms there will be high number of electrons causing a lower resistance because of the increase of the number of electrons. A wires resistance depends on four main factors i will investigate how the length of the wire affects the resistance.

Thx but this is not good for year ones they cant read you know should have some pictures thanks! This had really helped me with my year 9 work. No data is shared with facebook unless you engage with this feature.

I will then turn the power pack on and record what voltmeter and ammeter readings. 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. Overall, i think my method was sufficient to obtain reliable results. This is used to collect data on traffic to articles and other pages on our site. Wire 1, set 2 length (cm) voltage (v) current (a) resistance (w) (to 2 d. Non-consent will result in comscore only processing obfuscated personal data. Comments are not for promoting your articles or other sites. Resistance occurs when the electrons traveling along the wire collide with the atoms of the wire.

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

### Essay On Wisdom Speaks In Silence

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.

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.

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

### Essay Using Toulmin

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.

### Essay To Save Company Money

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
