As you can see in the graph, when the diameter of a wire is getting smaller which means a wire is getting thinner, the resistance goes up also, when the diameter of a wire is getting higher that means a wire is getting thicker, the [.

Resistance is a measure of how hard it is to move the electrons through the wire the length of the wire also makes a difference in the resistance because, 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. Resistance of a wire coursework essay the problem with using resistance as a measurement is that it depends not only on the material out of which the wire is made, but also the geometry of the wire if we were to increase the length of wire, for example, the measured resistance would increase. 387 words - 2 pages why is there resistance in wires, and when you vary things like the length of the wire, why does the resistance changethe best way to answer this is through an analogy imagine the charge that is flowing through a wire to be water flowing through a pipe.
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element in electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. 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 a wire we all know that current is the flow of electrons through an electrical circuit (the electrical charge), but before the electrons flow through the circuit, a voltage (or potential difference) must be applied this provides the pressure to push the electrons forward. Data analysis the investigation i did was to find the resistance of a piece if wire the piece of wire is my dependent variable throughout the investigation.

Physics gcse coursework: resistance of wire aim: to investigate if the length of wire affects its resistance prediction (hypothesis): i predict that the longer the wire the higher the resistance, and the shorter the wire the lower the resistance. Gcse physics 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. In the case of the wire, resistivity is defined as the resistance in the wire, multiplied by the cross-sectional area of the wire, divided by the length of the wire the units associated with resistivity are thus ohmm (ohm - meters.
Pressure, resistance, and flow this past weekend, i was out in the garden watering the flowers when suddenly the flow of water nearly stopped i looked behind me and realized there was a kink in. Resistance is the measure of how hard it is to get a current through a component in a circuit at a particular potential difference varying the resistance in the circuit can control the current through a circuit. I think that the reason for the thinner wire having such a high resistance is based on the make up of the wire the ions in the wire are a lot more tightly packed so there for it is harder for a larger flow of electrons to pass through the wire. - 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. Resistance of a wire - sample essay an electrical circuit was mounted using a power supply, an ammeter, a voltmeter and a resistor (wire) the voltage and current were worked out for different lengths of the wire using the ammeter (for the current) and the voltmeter (for the voltage.

It is this resistance which hinders the water flow and reduces both its flow rate and its drift speed like the resistance to water flow, the total amount of resistance to charge flow within a wire of an electric circuit is effected by some clearly identifiable variables.
Investigating the resistance of a wire planning for this investigation there are a number of variables that can be chosen to change or keep the same, these are. Below is an essay on resistance of a wire from anti essays, your source for research papers, essays, and term paper examples aim: to investigate how changing the length of the wire affects its resistance.
