Resistance Of A Length Of Wire Resistance
3,183 wordsThe four factors that affect the resistance of a piece of wire: Length, Diameter or thickness, Temperature and The type of metal. From thinking about how I would do this investigation and the outcome of it, I decided to use the length of the wire as the variable. Aim The aim of my investigation is to investigate how length affects the resistance of a length of wire Resistance is the force, which opposes the flow of an electric current around a circuit so that energy is required to push the charg...

Electrons In The Wire
509 wordsIntroduction Electric charge on an object is often called static electricity. Objects charge up because they gain or lose electrons. The electron is the smallest part of the atom. The electron carries a fixed negative charge. Every atom has a positively charged nucleus surrounded by electrons. An atom is uncharged because it contains equal amounts of positive and negative charge. Current is a flow of electrons. It is measured in amps. A circuit can be in series or parallel. In a series circuit t...

Length And Resistance In Experiment Two
1,732 wordsAim: The resistance of a wire depends on certain factors. Investigate the effect of two of these factors - Planning Some variables that will be relevant to this investigation are: Length Thickness Temperature Voltage Resistance Material Of these the variables will be input and output voltages in experiment one, and length and resistance in experiment two. The other variables (temperature, material and voltage) will have to be kept constant in both experiments to make sure that only length, thick...

More Wire The Charge
380 wordsInvestigating the effect of the length of wire on the current in a circuit Physics Coursework Plan I am going to set up the apparatus as shown in the diagram. I will measure the current with varying lengths using an ammeter. To keep it a fait test I will maintain the wire the same thickness and make sure the voltage is constant using a voltmeter. To make the experiment accurate, I will perform it 3 times, recording all 3 sets of results. The length of wire I use will be form 5 cm to 45 cm. Befor...

Resistance Of A Wire
2,359 wordsWhat is Resistance? Resistance is caused by collisions between the atoms in the object and the electrons (carrying electricity), which are trying to move through the object. (R = resistance measured in ohms (W) ). Basically resistance is the term used to describe an objects resistance to the flow of electricity Electrons lose their drift velocity only when they collide. The electrical resistance of a conductor is simply a measure of the potential difference required to maintain a current. Basica...

Resistance Of The Wire Against Length
688 wordsGCSE Physics SC 1 An experiment to investigate how the electrical resistance of a wire changes in relationship to its length- preliminary Prediction: I think that as the length of the wire increases so will the electrical resistance. Also I predict that my graph may have a strong positive correlation. I will also try to incorporate the equation y = m x + c. This will help me to find out the gradient of the graph. I predict that my graph my look something like this: Apparatus: Power pack Ammeter ...

Preliminary 2 The Changing Length Experiment
2,074 wordsPhysics Course Work Aim: The aim of this physics coursework is to find out the electrical resistivity of constantan by changing different variables. Factors that I will change or keep the same: Thickness of the wire Length of the wire The type of wire (copper, aluminium ect) Thickness: Keep length and the wire the same. Length: Keep the thickness and the material the same. Material: Keep the length and thickness the same. Predictions: I predict that the resistance will grow as we increase the le...
