Investigating the resistance of a wire

Observe changes to the equation and wire as you play with the resistivity, length, and area sliders sample learning goals predict how changing each variable will affect the resistance. A simple investigation of the factors affecting the resistance of a wire for each student group cells, 15 v, with holders, 2 crocodile clips, 2 ammeter (0 my objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire the factor i chose was length. Purpose the purpose of this investigation is to investigate whether variations in cross section areas of a wire (conductor) will affect its resistance i will be performing this investigation in the physic‟s lab using wires of different diameter 1 cripps, anthony c the electronics companion. If you are heating the wire with excessive current, that can change the readings fourth, your measurement of the wire lengths could be an issue the conductivity of the joint where the wire and meters make contact is another area.

Every electrical device has some resistance that is, when a voltage difference is applied across any two terminals of the device this model demonstrates how to compute the resistance of a short section of copper wire the convergence of the solution with respect to the mesh size is also studied. Investigating the resistance of wires class practical cyberphysics 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.

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 we then move the crocodile clip along by 100mm every reading. Then the connection wires will be connected to the cells until a firm reading of current and voltage is read this will only be a short time as it may begin to heat up as the electrons will flow quickly between 10cm of wire and will not take as long, which would cause my results to be inaccurate. Metal wires are made of millions of tiny metal crystals, and each crystal's atoms are arranged in a regular pattern when these electrons move, they create an electric currenti will investigate how the length of the wire affects the resistance i have done a preliminary experiment to help me decide the.

When the wire increases then the resistance will increase also this is because as there is more and more wire there are more obstacles for the electrons to go around objective for this piece of coursework i have been asked to investigate into the resistance of wires when the length is changed. Does the length of a wire affect its resistance googleusercontent search the thickness of the wire decreases two wires, same diameter, different what conductor movement electron gives rise flow current investigate how nichrome can affect did this so do not need cut every time all have just. In this investigation i am going to investigate what affect the resistance of a wire electricity flows in metals metal wires are made of millions of tiny metal year 11 physics investigation- what factors affect the resistance of a wire introduction we are trying to find out if the thickness of a wire affects. Investigating thickness2 and resistance graph 3 - relationship between the wire's thickness2 and its resistance conclusion i conclude that, as the length of a wire doubles, the resistance also doubles (provided the thickness of the wire is kept constant.

Investigating the resistance of a wire

In this piece of coursework i am going to investigate the resistance of a wire this will be done by performing experiments testing the wire under different conditions to see whether they affect the resistance knowledge i already have to help me complete this experiment is ohms law and how to. I will investigate the resistance of a wire in relation to its length prediction i predict that the longer the wire, the larger the resistance this is because the free electrons in the wire bump into more atoms, thereby making it harder for electricity to flow. Aim the aim of this investigation is to reveal that the factor of length affects the overall resistance so when changing the length of the conductor does resistance increase or decrease prediction i predict that as the length of the wire decreases so will the resistance.

The resistance of a conductor is a measure of how easy or hard it is for a current to flow through it 3 resistance ( ω) = voltage (v) in this investigation you measured the current in a circuit containing a length of wire you also measured the voltage across the wire when a current was flowing through it. Resistance is caused when these electrons flowing towards the positive terminal have to 'jumps' atoms so if we double the length of a wire, the 2 when investigating the length of the wire, i will firstly measuring the length of the wire with a ruler, so that my results are accurate and therefore the. Investigate the factors that affect the resistance of a wire we will write a custom essay sample on any topic specifically for you for only resistance is the measure of how difficult it is for the current to flow through a wire and was described mathematically by ohm in his famous law. Resistance of wires experiment by focus educational investigating the resistance of resistance wire gcse science.

Investigating the factors that affect the resistance of a piece of wire before commencing my investigation, i have taken into consideration several factors, which will affect the resistance of a piece of wire resistance occurs when the electrons travelling along the wire collide with the. In this investigation a circuit was created to investigate the changes in resistance by using different lengths of wire $attery with a voltage of %&v variable variables table variable wire length type independent how will you change it and what range of values will you use we will change the length. Read this full essay on investigating how the resistance of a wire changes with length aimthe aim of this investigation is to reveal that the factor of so when changing the length of the conductor does resistance increase or decreasepredictioni predict that as the length of the wire decreases so will.

investigating the resistance of a wire Introduction in this piece of coursework, i have been set the task of investigating factors that affect the resistance of a wire resistance is when travelling electrons in a wire collide with the atoms of the wire the collisions between the electrons and the atoms cause the electrons to move slower, which. investigating the resistance of a wire Introduction in this piece of coursework, i have been set the task of investigating factors that affect the resistance of a wire resistance is when travelling electrons in a wire collide with the atoms of the wire the collisions between the electrons and the atoms cause the electrons to move slower, which. investigating the resistance of a wire Introduction in this piece of coursework, i have been set the task of investigating factors that affect the resistance of a wire resistance is when travelling electrons in a wire collide with the atoms of the wire the collisions between the electrons and the atoms cause the electrons to move slower, which.
