    How does the length of a wire affect its resistance? Introduction: This first report in Physics will show the investigation of how the length of a wire affects its resistance. For starters I will go through the main definitions‚ to get a better knowledge of what is going to happen. However I will plan it out first to show each step of how I started‚ and then go into detail about the results and what the investigation on a whole has showed me. I shall then conclude my findings and present them with

    current when the length of wire changes‚ so I then can work out the resistance. I will be using constantan wire starting of with 1m length and then decreasing it by 0.10m intervals down to 0.20m long. I will not go above 1m or below 0.20m because it may be too long that they resist so much current that the wire burns‚ or the length of the wire is so small that it doesn’t resist any current at all. The length of the wire will be changed by moving the crocodile clip across the wire on a ruler. The independent

    An experiment to investigate the factors which affect Resistance in a wire What is resistance? A potential difference (V) applied across a wire of length (l)‚ there is in the conductor‚ an electric field (E). In this electric field the free electrons are not however under continuous acceleration (Ee/m). This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy. The vibrating atoms having gained this kinetic energy now vibrate more. The resulting

    Current and Resistance Physics Investigation Aim: Investigate how the length of a wire affects the current and resistance of a wire. Prediction and Hypothesis: I think as you increase the length of the Constatan wire‚ you also increase the amount of resistance. The current is the flow of electrons; the current is dependent on the amount of voltage‚ which is applied. Voltage is the push given to the current. The current has to go through a circuit‚ which contains resistance so if you increase

    OBJECTIVE For this piece of coursework I have been asked to investigate into the resistance of wires when the length is changed. INTRODUCTION The objective for my coursework (as already stated above) is to investigate how changing the length of wire can affect the resistance. There are factors which can affect how accurate our expriment is come on four levels. As in any scientific experiment‚ there are always variables ( "likely to change or vary subject to variation; changeable." ) which can

    Film: The wire (TV series 2002-2008) The series features the abuse of narcotics from a law enforcer’s‚ abuser’s and a drug dealer’s perspective. Rational choice theory This theory settles on a practical belief that man is an actor who reasons contemplates on benefits‚ means‚ costs and ends then makes a rational choice. Man has a sense comprehensible rationale of free will‚ where he evaluates the risks and benefits for committing a crime. From the excerpts from the film (season1)‚ we see a night

    Wire A wire is a single‚ usually cylindrical‚ flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Standard sizes are determined by various wire gauges. The term wire is also used more loosely to refer to a bundle of such strands‚ as in ’multistranded wire’‚ which is more correctly termed a wire rope in mechanics‚ or a cable in electricity. Although

    Coursework - Resistance of a Wire Coursework Introduction (Theory) In this piece of Coursework I am going to investigate the resistance in a piece of wire. Resistance is the force that slows down the flow of electrons; this can be due to electrons colliding. The total length of the wires will affect the amount of resistance. The longer the wire‚ the more resistance that there will be. This is also true for thickness of wire; the thinner the wire is the more resistance. Resistance is measured

    GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Electricity is conducted through a conductor‚ in this case wire‚ by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor‚ i.e. it has less resistance. For example‚ gold has more free electrons than

    How Does The Legnth Of A Wire Affect Resistance In A Circuit? Physics Investigation Aim: To measure how the length of a wire affects the amount of resistance when an electrical current is passed through it. Background Information: What is an electrical current When a full circuit is created (i.e. a continuous loop has been made connecting the negative end of an electrical source to the positive) it creates a path for electrons to pass through. These electrons need a "push"
