I decided to do five different lengths of wire and repeat each test three times. As the move along the longer wire they will collide with more metal ions.
This statement relates to the first graph only. To find the resistance you need to have the current and the voltage. My results were accurate, where most of the results were almost the same, which was good enough to plot into a graph that showed that my prediction was correct, which was done by following the method, where I have kept it a fair test and collect the results from the amps and volts carefully and accurately.
My teacher also helped me during the experiment. Prediction for preliminary work I think that if I make my wire longer the resistance will increase. What Factors Affect the Resistance of a Wire? I could also change the way in which I measured the resistance. 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.
R 7 Analysing results My results support my predicted statement: Electric current is a flow of electrons, and it is these electrons that collide with the nucleus of the atoms.
I would have understood if all the graphs for constantan would be straight-line but it was only one graph of varying length out of three graphs of varying length.
Electricity is conducted through a conductor, in this case wire, by means of free electrons. The resistance of the wires varied with the temperature, which also shows why my preliminary work went wrong. Set the multi-meter to the Ohmmeter setting.
The reason for these odd results can be justified by saying that as the resistance increases the energy is converted to other forms of energy, such as heat and light energy. As the length of the wire decreases and the thickness increases, the resistance decreases and the current increases.
By looking at my graphs, I can see that in the graph showing the resistance of the thickness of a wire, a line gradually curving up to the right hand side from the bottom left, which means there is a gradual increase in resistance from the width of 0.
Wire is made up of atoms. Length of the wire.THE FOUR FACTORS THAT AFFECT THE RESISTNCE OF A WIRE ARE: 1. LENGTH OF WIRE. 2. THICKNESS OF WIRE. 3. TEMPERATURE.
4. TYPE OF METAL. AIM: To investigate how the length of a Nichrome wire can affect the resistance of a wire. PREDICTION: In my opinion the longer the wire the more resistance there will be. Essay on Factors Affecting the Resistance of a Metal Wire - Factors Affecting the Resistance of a Metal Wire 1.
Investigate some of the factors that affect the resistance of a metal wire.
The current and voltage will be measured and then V = IR will be used to calculate the resistance. What Factors Affect the Resistance of a Wire? Planning Background Electricity flows around a circuit in a current.
A current is the flow of electrons. Essay about Factors Affecting the Resistance of a Wire - Factors Affecting the Resistance of a Wire The aim of this experiment is to investigate one factor that affect the resistance of a wire.
I will do this by performing an experiment. First I will need to identify the factors that effect resistance. Factors Affecting The Resistance Of Wire Aim: To investigate the factors that affect the resistance in a conductor.
The main factors that affect the resistance in a conductor are: · Length · Temperature · Cross sectional area · Material · Magnetism The factor that. An investigation into the factors affecting the resistance of a wire Outline: Start with a simple paragraph saying what you are going to do.
Factors affecting resistance of a wire: Material, Temperature, Length and Cross-sectional area Material is the same (constantan) and we are trying to .Download
