Introduction The resistance of a wire depends on certain factors. Some of these variables are listed below: Length of wire Diameter or thickness of wire Temperature at which wire is kept The material of which wire is made out of. The potential difference or voltage. Humidity Cross sectional area. Voltage across circuit All these factors will have to be kept constant except the diameter of the wire whilst doing the experiment to ensure that the investigation is

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

Baldeo Persaud NT1310 Physical Networking Unit 4 Assignment: 1 Copper vs. Fiber In this paper we will discuss two different cabling solutions (copper & fiber)‚ and in what situations you would choose one over the other. One might be better for one type of application while the other might be a better fit‚ depending on the situation. They each have their own advantages which we will discuss in the following paragraphs. The first type of cable we will talk about is copper cabling. There are three

the resistance of a piece of wire; the one I am investing is the length at constant temperature. 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. Factors: There our four different things that affect the resistance of a wire: 1. The Length because the wire is thinner than the rest of the wires the electrons wood have more trouble going through for if the wire had the same width there would

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 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

Petit: Sane Wire Walker What do you think when you imagine a man walking on a wire higher than 10 stories high? A French wire walker named Philippe Petit walked over many structures from Notre Dame to Sydney‚ Australia‚ to New York. Through the things he has done‚ people may think he is crazy. However‚ Petit and I think that there is nothing crazy about what he has done. I believe the people/society thinks he is crazy. They see this man up hundreds of feet walking across a wire over famous

Worldwide Wires “Revenue Recognition Woes” Introduction Worldwide Wires (“WW”) is a company that provides computer network and communications services around the globe. The company offers its services either directly to the customer or through a network of partners that are scattered around the globe. Their business model can be compared to that of a principal and an agent‚ with WW being the former and the partners being the later. The company and the partners enter into 5 year service agreements

did a great job of depicting just how much Philippe appreciated every minute of his life. Philippe not only enjoyed the planning of his wire walk and the adrenaline rush of having to tiptoe around all the security guards patrolling the towers‚ but also the act of setting everything up. We can see this in his expressions‚ during his first few minutes on the wire his face shows complete concentration and then only a few moments later he is peaceful‚ the euphoric expressions on his face tell the story
