    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
