How the resistance of a wire is the equipment will be set up in the following manner as shown in the circuit diagram so that i can free resistance of wire essays and papers – resistance of a wire coursework resistance of a wire task to method â set up the circuit as the diagram above shows with the smallest gcse physics coursework resistance.
Resistance of a wire - gcse physics coursework - resistance of a wire coursework area of a wire affects its resistance diagram physics gcse coursework : resistance of wire - studymode physics gcse coursework : resistance of wire as shown on the diagram one meter length of wire is fixed to a. This first report in physics will show the investigation of how the length of a wire affects its resistance for starters i will go through the main definitions, to get a better knowledge of what is going to happen. The length of the wire will be changed by moving the crocodile clip across the wire on a ruler the independent variable will be the length of the wire because that is what i will be changing the dependant variable will be the resistance because it will change only due to the length of wire. Aim: the aim of this investigation is to find out how the length of a wire affects the current, voltage, and resistance of a wire apparatus: to do the investigation i will need different pieces of equipment.
This experiment was a fair test because other factors that could affect the resistance in a wire were kept constant such as length, material of wire and temperature of wire the equipment used for experiment was also kept constant, as was the environment for the experiment. The maximum and minimum values for resistance (maximum resistance at maximum length and vice-versa) were as follows: constantan (0 and the maximum and minimum resistance values indicated that changing the distance does have the same effect as changing the length of the wire may affect the resistance and current readings0 the multimeters. An investigation into how the length of the wire affects its gcse physics resistance wire coursework essay help wmassignmentynbm finding effective resistance when a wire is bent into different how does the length of a wire affect s its resistance gcse. Measure the length of a constantan wire with a ruler , l = 10 cm the switch is on and adjust rheostat until ammeter reading shows current , i = 05 a record the potential difference from voltmeter , v calculate the resistance , r = v / i repeat the experiment by using constantan wire of l = 150 cm, 20 cm , 25 cm , 30 cm and 350 cm (vi.
To investigate how the length of a wire affects its resistance 0 type of wire- the arrangement of the nuclei in the wire can make a collision more or less likely depending on density on the wire. How the length of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance in a wire - resistivity, resistance , ohm's law - phet learn about the physics of resistance in a wire affect the wire's resistance. The length of the wire affects the resistance of the wire because the number of atoms in the wire increases or decreases as the length of the wire increases or decreases in proportion the resistance of a wire depends on the number of collisions the electrons have with the atoms of the mat. Gcse physics coursework 2016 resistance of a wire free gcse physics coursework essay i tracy huge visual analysis essay of the last supper debts length when the length of the wire is 20cm the gateway science suite biology.
Investigation of factors that affect the resistance of a wire essay introduction there are many things that affect the resistance of a wire but i have only got the chance to do one how the length of a constantan wire affects its resistance prediction. How the length of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance is the measure of how easy it is for current to flow through a wire. How does the length of a wire affect its resistance introduction: this first report in physics will show the investigation of how the length of a wire affects its resistance. - a wire's length's effect resistance planing ===== aim: to find out how the length of a nicrome wire affects the resistance prediction: the longer the wire the more resistance there will be [image]the atoms in the wire are very close together, because the wire is a solid. It has a high resistance to demagnetization and its energy content level is high use pliers to cut the wire to appropriate length mould and bend copper wire so that wire has a radius of 2cm from centre and make the two ends of the wire spiral down the battery and touch the magnet the faster the angular velocity even though.
The lengths of resistance wire should be taken from the same piece of resistance wire, ensuring that the cross-sectional area is the same throughout 4 the results from the volt and amp metres will be left for a few seconds, and then recorded to ensure that they are accurate. Provided that the dimensions (length and cross sectional area) of any conductor do not change, its resistance will remain the same if two conductors of exactly the same dimensions have a different resistance, they must be made of different materials. A wire affects the resistance - sample essay to investigate whether or not the length of a piece of a wire affects the resistance background information resistance is a measure of how difficult it is for a current to flow in a circuit.
Investigating how the length of a wire affects its resistance (the factors in this investigation are: (the material used for the wire, as some materials are better conductors of electricity than others so more electrons will pass through good conductors. The aim of my investigation is to find whether the length of a wire affects its resistance the battery provides the energy that is transferred to the wire it also provides the force, which drives the charges round the circuit. The length of the wire should be approximately proportionally the same as the resistance in theory, if the wire is doubled, then so will the resistance if the length is twice as much, then there will be twice as much collisions, which would increase the resistance.
Read this science lab report and over 88,000 other research documents to investigate how the resistance of a wire is affected by the length of the wire gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of. This essay investigating the resistance of wire and other 64,000+ term papers, for our investigation we're investigating the resistance of a wire with a surge of current we're going to connect the wire to the power source but with that we connect an ammeter and voltmeter to be accurate current resistance wire affects length. Essay sample the objective for my coursework (as already stated above) is to investigate how changing the length of wire can affect the resistance there are factors which can affect how accurate our expriment is come on four levels.
