affects the resistance of a piece of wire. Wire is made up of atoms. Electric current is a flow of electrons‚ and it is these electrons that collide with the nucleus of the atoms. Every time this happens‚ it causes resistance. The build up of friction is what produces the heat. There are many variables that could affect the resistance of the piece of wire: Length Potential difference Tension Temperature Diameter Shape Material of the wire I have chosen to do length because

investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light bulb. How is it measured? The resistance of a length of wire is calculated by measuring

resistance of a wire Introduction: Resistance is a force‚ which opposes the flow of an electric current around a circuit. Resistance is measured in Ohms. George Ohm discovered that a circuit sometimes resists the flow of electricity. He called this ’RESISTANCE.’ He even came up with a rule for working out the resistance of a circuit‚ which was: R= V ÷ I V- Volts I- Current R- Resistance Ohms law says the more resistance means more energy is needed for the current to pass through the wire. Resistance

Hirschi’s Social Bond Theory Describes D’Angelo Barksdale in The Wire Travis Hirschi’s dissertation‚ which eventually became a well-respected and commonly used book in criminology‚ had within it one of the most influential theories of crime that was tested with data and supported with results. The dissertation became known as Causes of Delinquency and was published in 1969 (Kozey‚ 2012). The general theory states that delinquency takes place when a person’s bonds to society are weakened or broken

How does Steinbeck’s writing make the fight‚ a powerful and significant moment in the novel? Steinbeck uses many ways to make the fight powerful and significant; he makes things in the scene fast paced‚ from where Curley sees George smiling‚ to him starting the fight and Lennie getting beaten up‚ to Lennie crushing his hand. Yet Steinbeck stretches the fight over 2 pages and a bit‚ where as it would have probably lasted less than 30 seconds which shows it’s a significant piece and amongst it there

Moonlight shines through his small‚ square‚ four paned window- the only view of the outside world. Gleaming stars twinkle above in the American sky and the misery on Crooks’ face is indescribable.

Chapter Analysis Chapter One Two itinerant workers‚ George and Lennie‚ are introduced. They rest in a small clearing by the Salinas River‚ on their way to a nearby ranch where they expect to sign on for work. They have hurriedly left the last ranch‚ following an incident involving Lennie in Weed. Lennie pleads with George to tell him over and over again about their dream ranch‚ where Lennie’s main task will be to tend the rabbits. Lennie’s Aunt Clara‚ whom he refers to as “that Lady”‚ is briefly
