An Investigation into Factors Affecting Resistance of a Wire Plan: The possible variables I could use to find out factors affecting resistance are material wire is made of, length of wire, temperature and cross sectional area of wire. I will use cross sectional area of wire and length of wire because I think it will be hard to draw conclusions from the material of wire. I am not doing temperature because it would be hard to get results from and I think they wouldn't be as accurate.
An Investigation into the Relationship Between the Resistance of a Wire and Its Diameter and Length Introduction In this investigation I hope to see whether there is a relationship between the thickness of a wire and its length with the resistance in which it produces. First of all, what is resistance? Resistance is calculated as R=V/I Where R is resistance, V = Potential Difference (Voltage) and I = Current (Amount of charge flowing per second) Resistance is the property of a conductor
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

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
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
Investigating How Length and Width of Copper Wire Affect the Current of a Circuit Task: To investigate how length and width of copper wire affect on the current of a circuit. Prediction: In this experiment, the input variable will be changing the length of the copper wire used in the experiment, and also the SWG of the wire, which means the width of the wire. By changing this variable, the current the circuit will vary. With my knowledge in science and some
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
Factors that Affect the Current Needed to Melt a Wire Aim: Investigate one factor that affects the current needed to melt a wire. Plan: I am going to investigate what factors affect the current needed to melt a wire. In this investigation, I have decided to change the thickness of the wires that I use, and then while increasing the resistance, I will measure the current needed to melt the different wires. I will start with the variable resistor set to the maximum. I will slowly decrease
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
Aim: To investigate factors which affect the strength of the electromagnet and make the strongest electromagnet possible. Apparatus: · Iron Rod · Leads · Power Pack · Crocodile Clips · 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
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
frustration and depression. 4. ELF radiation- Elf stands for extremely low frequency. Electro-magnetic fields cause this. VDU screens give out radiation at the back and sides. 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
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
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
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
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
