Investigating How Different Lengths of Wire Affect the Resistance in a Circuit Hypothesis: I predict that; the longer the wire, the more resistance there will be. So if the length of the wire were to double, so would the resistance. The reason for my prediction is: The flow of electrons is called a current, the electrons are constantly hitting atoms, which causes resistance. If the same amount of current is passed through a longer piece of wire, there will be more collisions, hence more
The Length of a Wire Affects Its Resistance Scientific Enquiry: I know that metals are good conductors of electricity. Metals are good conductors because their electrons are easily released allowing electricity to flow. The electrons can carry current because they split up from the positive ions, so they are free to move and to carry current. Factors that affect resistance: 1. Length – the longer the wire the more atoms there are for the current to push through. 2. Width –
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
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
How Thickness and Length Affect the Resistance of a Wire I plan to investigate how the length and thickness of a wire affects the resistance. I plan to do this by keeping the voltage the same by using a variable resistor and measure the current when varied lengths and thicknesses of wire is in a circuit ===================================================================== Variables ========= There are a few factors that can affect the resistance. These are; * Temperature
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
Investigating the Factors that Affect the Resistance of a Wire Aim To study the factors which affect the resistance of a wire. Background Information Although current and potential difference measure different things, they are related to each other. In 1826, Georg Ohm discovered that doubling the p.d. doubled the current. (Taken from Ohm's Law: the current flowing through a metal wire is proportional to the potential difference across it (providing the temperature is constant)
Investigating How the Length of a Wire Affects Its Resistance Planning: Risk Assessment: * I will handle the power supply carefully. * I am going to only use a maximum voltage of 2 volts. * I will be careful when handling the mains equipment. * I will make sure I have a clear space to work in and nothing on the floor around me. In this investigation, I will set up a simple circuit to be able to read the voltage and current when the length of wire changes, so I then can work out
saloons and rides off into the sunset. However, the characters of the West weren’t the only things that helped the development of America; many inventions were a part of the development of the West and helped it flourish into a thriving community. Barbed wire, the McCormick reaper and railroads—for example—were a large part of the development in the West—from helping to define claimed land boundaries, agricultural development and competition, and even growth of the West. Claimed land boundaries could only
Investigating How the Length of the Wire Affects the Resistance of the Current Passing Through Wire Aim For this experiment, my aim is to investigate how the length of the wire affects the resistance of the current passing through the wire. Hypothesis and Scientific Knowledge When electric current passes through a conductor, there is always a resistance against it. The resistance varies between different types of materials. Although all metals are conductors, some have a higher resistance
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

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
Measuring the 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
Factors that Affect the Strength of the Electromagnet 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
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

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
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
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
