Physics coursework objective: my objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire the one i am investing is the length at constant temperature. These results show that as the length of the wire increases, the resistance increases, as well furthermore, if you double the length of the wire, the resistance is roughly doubled for example, when the length of the wire is 20cm the resistance is 314 ohms when the length of the wire is 40cm the resistance is 618 ohms, which is roughly double. We can see how resistance increases and so does voltage the graph is a straight line graph, showing that length of wire, resistance and voltage are directly proportional to one another (the voltage doubles, so does the resistance) using this graph, we can predict the resistance of any length up to 100cm. How the length of a wire affects its resistancein 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.
Read this science essay and over 88,000 other research documents resistance of a wire investigation preliminary investigation: aim: to investigate the main problems with my main experiment and to see how to resolve these. Planning in this piece of coursework, i am going to investigate what affects the resistance of a piece of wire wire is made up of atoms electric current is a flow of electrons, and it is these electrons that collide with the nucleus of the atoms. Factors affecting the resistance of a wire introduction: resistance is a force, which opposes the flow of an electric current around a circuit resistance is measured in ohms.
The aim of this experiment is to find out if the resistance of a piece of wire will change if we vary the length to do this i will set up a circuit that will include an ammeter, a voltmeter and a piece of wire. In this piece of coursework, i am going to investigate what affects the resistance of a piece of wire wire is made up of atoms electric current is a flow of electrons, and it is these electrons that collide with the nucleus of the atoms. Essay editing help an experiment to determine wire resistance with varying wire diameter 3,909 words 9 pages the resistance of a piece of wire.
Resistance in a wire coursework in this investigation we are trying to look for resistance in a piece of wire, and how the length of a wire can increase or decrease the resistance. Physics investigation resistance of wire essay while the free essays can give you inspiration for writing, they cannot be used 'as is' because they will not meet your assignment's requirements if you are in a time crunch, then you need a custom written term paper on your subject (physics investigation resistance of wire . An essay or paper on electrical resistance: an overview resistance, in electricity, is a property of any object or substance to resist the flow of an electrical current the quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. It is this resistance which hinders the water flow and reduces both its flow rate and its drift speed like the resistance to water flow, the total amount of resistance to charge flow within a wire of an electric circuit is effected by some clearly identifiable variables. Resistance = potential difference (in v) current (in a) there are four main factors that effect resistance, these are: as temperature increases, the resistance of the wire increases as well some metals are better conductors than others, for example nichrome has more resistance than copper.
Resistance of a wire essaysaim: the resistance of a wire depends on certain factors investigate the effect of two of these factors ¡v some variables that will be relevant to this investigation are: of these the variables will be input and output voltages in experiment one, and length and resis. Resistance occurs when the electrons travelling along the wire collide with the atoms within the wire these collisions slow down the flow of the electrons, causing resistance resistance is a measure of how hard it is for the electrons to flow through a circuit. Below is an essay on resistance of a wire from anti essays, your source for research papers, essays, and term paper examples aim: to investigate how changing the length of the wire affects its resistance. A piece of wire upon its resistance - sample essay for my investigation i will examine the effect that the length of wire has on the resistance for a given current here is a simple diagram explaining the variables in this experiment: i predict that if i increase the length of the wire then the resistance will also be increased producing a.
To experiment whether the length of a piece of nichrome wire affects the resistance in a circuit containing two batteries, a voltmeter, and an amp meter. I think that the reason for the thinner wire having such a high resistance is based on the make up of the wire the ions in the wire are a lot more tightly packed so there for it is harder for a larger flow of electrons to pass through the wire. Remember that resistance occurs when the electrons travelling along the wire collide with the ions of the wire also remember when the resistance is increased, the current will decrease resistance is a measure of how hard it is to move the electrons through the wire.
Thickness (cross sectional area of the wire), length, and temperature all have some effect on the amount of resistance created in a wire another factor is the conductivity of the material we are using 1 / 262: resistance coursework - some useful things planning: aim investigate how the length of a wire affects the current and resistance of a wire.
