To investigate how the resistance of a wire is affected by the length of the wire to read essay to investigate how the resistance of a what affects the . Wire resistance essay examples an investigation of the factors that affect the resistance of a wire the resistance of a piece of wire. This is the resistance and if the wire is long it will have more wire to slow the electrons down and then the current, resulting in more resistance we will write a custom essay sample on what affects the resistance of a piece of wire specifically for you.
Investigating the factors that affect the before commencing my investigation, i have taken into consideration several factors, which will affect the resistance of a piece of wire i will gradually work through these particular factors in my preliminary experiment, to eliminate erroneous parts of . Free college essay resistance of a piece of wire planning in this piece of coursework, i am going to investigate what affects the resistance of a piece 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.
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. - temperature when a wire is heated, the atoms in the wire vibrate because of their increased energy this causes more collisions, and collisions slow the rate of flow of electrical charge through the circuit, and so cause more resistance. Affect the resistance of a piece of wire the one i am investing is the length at constant temperature my objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire . Introduction in this piece of coursework, i have been set the task of investigating factors that affect the resistance of a wire there are many things that affect the resistance of free essays must be free.
Let the resistance r of a piece of wire be a thermometric property for measuring t assume that r = at+b where a and b are constants the resistance of the wire is found to be 5 ohms when it is at the temperature of melting ice and 6 ohms when it is at the temperature at which water boils at atmospheric pressure. An electronics instructor wants to demonstrate to his students the effect of electrical resistance changing with temperature to do this, he selects a carbon resistor about 3 centimeters in length and 5 millimeters in diameter, black in color, with a wire at each end, and connects it to an ohmmeter. We will write a custom essay sample on resistance of a wire as temperature increase can also affect the results a wire affects the resistance a piece of . An investigation into the resistance of a wire free gcse physics coursework essay investigate what affects the resistance of a wire using a new piece of . The resistance of a typical conducting wire is low when temperature is low and high when temperature is high the increase in resistance alongside temperature is due to an increase in energy of the wire atoms, which cause them to vibrate more and impede the path of the electrons flowing through a .
We will write a custom essay sample on how temperature affects resistance on a piece of wire specifically for you for only $1638 $139/page. Factors that would be affect the resistance of the graphite are length, cross sectional area and temperature as the length of the conductor is shorter it would allow more electrons to pass through at a higher rate rather than a longer one. Mark, the short answer is: the longer the wire, the larger the resistance more detail: resistance is a measure of how difficult it is to push electrons (the particles that carry electrical current) through a wire the larger the resistance, the more force you have to apply and. I predict that the shortest piece of wire will have the least resistance and the longest piece of wire will have the greatest resistance during this investigation my controlled variables will be the other factors which affect resistance: cross-sectional area, temperature and the material of the wire. Introduction: in this coursework investigation, i will be doing a series of experiments to see how changing the length of a piece of wire affects the resistance of the wire prediction & background theory: i predict that as the length of wire becomes longer, the resistance.
Resistivity and laws of resistance , electrical resistance r of a conductor or wire is where, ρ the temperature of the substance also affects the resistance . What affects the resistance of a piece of wire - sample essay we could see how temperature affects resistance, although, one would need to have done a constantan . How is resistance affected in a wire essay a+ text this student written piece of work is one of many that can be found in our gcse electricity and magnetism .
Factors that affect the resistance of a wire the resistance of an object is a measure of the how reluctant current is to flow through that object it is given the symbol r and has the unit w (which is a greek letter omega and pronounced 'ohm'). Does temperature affect conductivity and resistance will study whether the temperature of a wire will affect the then measure the resistance, and temperature . Factors which affect the resistance of a wire essay at a given temperature, the resistance is proportional to same piece of wire throughout the whole . An experiment on the effects of an increase in the length of a nichrome wire on its resistance pages 5 words view other essays like this one: company.
