Resistance of a Wire Experiment 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 iron and, as a result, it is a better conductor. The free electrons
Factors Which Affect the Resistance of a Wire To start off this experiment I feel that it is suitable to explain the main facts of this study. Below is a section explaining the resistance in detail. Facts on Resistance: I have shown how resistance occurs. · WIRE · ATOMS · ELECTRONS Resistance occurs when the electrons traveling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing resistance. Resistance is a
Relationship Between the Resistance and the Length of a Wire Aim: To find the relationship between the resistance of the wire and the length of the wire Background Factors: i. Temperature : If the wire is heated up the atoms in the wire will start to vibrate because of their increase in energy. This causes more collisions between the electrons and the atoms as the atoms are moving into the path of
The Relationship Between Length, Width and Resistance of a Wire Aim: To investigate how the length and width of a wire affects the resistance of the wire. 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. gold has less resistance. For example, gold has more free electrons than iron and, as a result, it is a better
Resistivity of a Wire Aim The aim of this experiment is to find out how the area of the cross section of the wire affects the resistance and also to find out the resistivity of the wire having found the resistance over a certain length and using a certain cross sectional area. I will also experiment to see how the length of the wire affects the resistance. Plan The first thing that I will do is to set up the apparatus as shown below. A,V Except for the experiment where I alter
Insulated Wire · Iron Nails · Voltmeter · Plastic Beakers · Electronic Balance Hypothesis: I expect the strongest electromagnet to have a 'soft' iron core; the highest number of coils (45); the strongest voltage (10V) and current and have the coils evenly spread across the iron rod. The 'soft' iron core means it changes easily between being magnetised and de-magnetised, it is perfect for electromagnets, which need to be turned on and off. From a previous experiment, using an
a piece of graphite paper is affected by the width of it. The aim of the investigation is to carry out a suitable experiment to find various different resistances for various different widths of graphite paper. Preliminary Experiment The purpose of the preliminary experiment is to find a suitable length of graphite paper to use in the real experiment. For this experiment we will be using a 0-1mA shunt as I think it will give the best deflection. Ideally we wanted to find a length of graphite
The Wire is structured both horizontally and vertically, from the foot soldiers of the drug trade, through the school system, newspapers, police department to the higher executives in charge of everything, which shows the parallel and prevailing problems that plague all of society. The show provides a viewer with an insight into the steep decline in social order, in which cops, politicians, teachers, workers and criminals are surrounded by the corrupting forces that overwhelm them all. The Wire tells
The Relationship Between the Length of Constantan Wires in a Circuit and the Current Aim To investigate the relationship between the length of constantan wires in a circuit and the current flowing through. Introduction ============ In a conductor electrons are able to jump between atoms. However in insulators they remain around a single atom unable to move. Constantan, a metal, unlike most other metals is a poor conductor although it is also a poor insulator. Being a metal it
Resistance of a Wire Aim Which factors affect the resistance of a wire? Prediction I believe the factors which affect the resistance of a wire are: 1. The length- the increase in length could increase the resistance. 2. The thickness of the core. 3. The material of which the wire is made up of- e.g. Copper, constantan and nichrone. 4. The number of strands within a wire: 5. The amount of current flowing through the wire. For this experiment, the factors which will be
Resistance of a Wire Introduction: In this piece of coursework, I have been finding out factors that affect the resistance of a wire. Firstly, I will explain how resistance works. Resistance is when electrons in a wire collide with atoms also in the wire. When the electrons and the atoms collide the electrons start to move slower, which then causes resistance. So, resistance is how hard it is to move electrons through a wire. Now, I am going to tell you what are the factors of wire resistance
the two media, it is important for organizations to use both of them to capitalize on the benefits or advantages of each. Generally, wired media is media used to transport information through a network that involves the use of physical pathways i.e. wire. The most common types of wired transmission media include telephone cables and coaxial cables. With regards to computer networks, a wired home network involves connecting the computer or other related devices to a Super Hub with an Ethernet cable

Pregnant women are at most at risk. 5. Lose wires- are a hazard as anyone may trip over the wires and fall over Ways to combat the mentioned problems 1. RSI- The risk of RSI can be minimised if a computer user is able to sit in a comfortable, upright position when working. To be able to do this they need adjustable
Installing Car Audio When a person gets into a car, one of the first things they do is turn on the radio. Some people like the volume turned down real low and others like myself want loud blaring music. There are several steps to turn a factory sound system into a surround sound theatre. I have installed all kinds of car audio equipment into automobiles and it doesn’t come cheap. First thing anyone wants to do is to set a price range and compare prices at different retailers. The price range
contradictory image of an ideal lover. The speaker insisted that his "mistress' eyes" were "noting like the sun. Coral" was "far more red than her lips' red" and "if snow be white," then "her breasts" were "dun." He also commented that "if hairs be wires, black wires" grew "on her head." Furthermore, her skin was dark and not smooth; her breath was unpleasant too. These descriptions summe...
came from the telegraph. The word telegraphy comes from Greek. "Tele" means distant and "graphein" to write. So the meaning is writing at a distance The first form of modern telecommunication - the electric telegraph - sent electrical currents along wires. On 24 May 1844, Samuel Morse sent his first public message over a telegraph line between Washington and Baltimore, and through that simple act, ushered in the telecommunication age. By 1868 Jamaica began to use the telegram. The West India and Panama
Tips for Making Meetings Effective Throughout a project-oriented deployment, you will be required to conduct numerous meetings with your customer. If you plan them properly, you will be able to steer the project in the right direction. It also gives you the ability to gather all the key players in one room, put them on the same page, work through any issues that might have arisen and make any decisions that need to be made. When I first started running my own projects, I was given some great tips
The Resistance of a Wire Introduction In this investigation I will be trying to find out the resistance of a piece of constantan wire. I know that according to ohms law, the p.d is proportional to the current so if the p.d doubles so will the current. Through past experiments I know how to work out resistance, to work it out I use this formula Where the resistance is R, the p.d is V and the current is C, from this you can work out the resistance of any circuit. Aim of the Preliminary
aesthetics of the rental house. Most of the wires are run in the attic and then down plastic conduit attached to the wall. The conduit is run all the way to the wall boxes where the Ethernet ports are located. Every wire is clearly labeled and included in an easy to read schematic of the house. This way future tenants will have the ability to utilize the network. Next, every room needed to have access to the network. In order to minimize the overall use of wires, hubs were placed in strategic locations
