Resistance Investigation Introduction Electricity is something we have all around us every day but we never really think about it, even though it is such an important part of ours life’s. What is electricity? Before investigating the resistance of different metals it is important to understand the principal of electricity. Electricity is formed by the movement or flow of electrons being attracted away from their atoms by an applied force. This is easier to do with the some elements

Satisfactory EssaysWire Resistance Investigation Planning -------- Aim --- In this experiment the resistance change in a wire will be investigated. I will be investigating if the thickness or cross-sectional diameter of the wire affects the resistance. Variables --------- The input variable will be the thickness of the wire to the nearest millimetre. The output variable will be the readings on the ammeter and voltmeters. The controlled variables will be the length of wire and the current

Satisfactory EssaysInvestigation of The Resistance of Wires The Experiment ============== The experiment that was used to obtain the results was very simple. The voltage and current were measured whilst varying the length of wire. The results for voltage and current were recorded along with the diameter of the wire. This allowed for a range of other values to be calculated, including cross-sectional area and resistivity. [IMAGE] The Equipment * A power supply * A voltmeter and an Ammeter

Satisfactory EssaysResistance of Wire Investigation Aim To investigate the resistance of a metal wire depending on its length. Introduction ============ An electric current is the flow of microscopic particles called electrons through wires and electronic components. It is like the flow of water through pipes etc. As water is pushed through pipes by a pump, electric current is pushed through wires by a battery. One thing we know is that like charges repel each other and unlike charges attract

Satisfactory EssaysResistance of Wire Investigation In this investigation we are going to test our theory in relation to resistance of the wire. We have predicted that the longer the length of the wire the greater the resistance will be, we have predicted this because of our theory of resistors in series. In a wire there are both atoms and electrons the electrons move from the positive terminal of the cell to the negative whilst the molecules move vice versa. When the circuit is switched on and voltage

Satisfactory EssaysResistance of a Wire Investigation Introduction In this investigation I will carry out an experiment to distinguish how the length of a wire, disrupts the behaviour of the resistance. Throughout this investigation I will include my prediction, method, diagram, results and a graph to show the relationship between the length of the wire and the resistance. Remember that resistance occurs when the electrons travelling along the wire collide with the Ions of the wire. Also remember when

Satisfactory EssaysPhysics Investigation Of Resistance Aim: To investigate how the electrical resistance of a wire changes in relationship to its length. Prediction: I predict that as the length of the wire increases so will the resistance of it. I also predict that the rate at which the resistance of the wire increases will be directly proportional to the length that is increased each time. Hypothesis: As the length of the wire is increased, the number of collisions between the current carrying

Satisfactory EssaysResistance of a Wire Investigation Resistance is to do with how easy it is for the electric current to flow through a material, e.g. a piece of copper wire. Some materials have virtually no resistance when they are cooled down to absolute zero, they are called super conductors. Mercury will do this. Materials like plastic, wood, polythene, ceramics and rubber have very high resistances so that it is almost impossible for electric currents to flow through them. These materials are called

Satisfactory EssaysBackground Knowledge Resistance, in electricity, is a property of any object or substance to resist the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. The resistance of an object is determined by the nature of the substance of which it is composed, its resistivity, accounting for its dimensions and its temperature. Resistivity is expressed in terms of Ohms / cm3
