Physics investigation resistance of wire essay while the free essays can give you inspiration for writing, they cannot be used 'as is' because they will not meet your assignment's requirements. 12 immediately measure the resistance of the wire using an ohm metre ensure that the recording is taken immediately, to ensure that the results are as accurate as possible recording the data 13 disconnect the battery from the circuit 14 then measure the resistance, and temperature of the wire 15 re-connect the battery to the circuit 16. Two factors that affect the resistance of wire are, the length of the conductor and the circular mill area of the conductor the third factor is the metallic element from whic h the conductor.
Factors affecting the resistance of a wire - sample essay resistance is a substance of resisting the flow of an electrical current the quantity of resistance in an electric circuit. An investigation into the resistance of a wire - a grade gcse physics coursework in this investigation i am going to investigate what affect the resistance of a wire conductors have resistance, but some are worse than others. The aim of this experiment is to investigate the ways in which thickness (or rather the cross sectional area) affects the resistance of a wire, how it affects it, and why this happens.
- investigating factors affecting resistance of a wire aim --- investigate what factors affect the resistance of wire, however in this experiment i am going to monitor how the length of a wire affects the resistance of a wire if the current is kept the same. If i had a 30 cm wire and a 60 cm wire, the 60 cm wire would have a resistance twice that of the 30 cm wire for this experiment i will be using a voltmeter, an ammeter, five wires, two crocodile clips, some nichrome and copper wire and a power pack. What factors affect the resistance of a wire planning background electricity flows around a circuit in a current a current is the flow of electrons. There are four basic factors of inductor construction determining the amount of inductance created these factors all dictate inductance by affecting how much magnetic field flux will develop for a given amount of magnetic field force (current through the inductor's wire coil): number of wire. The suffix letters f and a are added to the ends of wire factors affecting insulation resistance factors that affect cable insulation resistance.
A resistor is a little package of resistance: wire it into a circuit and you reduce the current by a precise amount from the outside, all resistors look more or less the same as you can see in the top photo on this page, a resistor is a short, worm-like component with colored stripes on the side. For example, when the length of the wire is 20cm the resistance is 314 ohms when the length of the wire is 40cm the resistance is 618 ohms, which is roughly double in my main investigation i will see if this observation applies to my results. Factors that affect the resistance of a wire the resistance of an object is a measure of the how reluctant current is to flow through that object it is given the symbol r and has the unit w (which is a greek letter omega and pronounced 'ohm'. The longer the wire, the more resistance that there will be there is a direct relationship between the amount of resistance encountered by charge and the length of wire it must traverse after all, if resistance occurs as the result of collisions between charge carriers and the atoms of the wire, then there is likely to be more collisions in a.
The resistance of a wire depends on 3 parameters: the conductivity of the material from which the wire is made, its cross sectional area, and its length highly conductive materials, such as copper and silver, are used to manufacture wire to achieve a low resistance. An investigation into the factors affecting the resistance of a wire pages 3 words 922 view full essay thickness of the wire, lenth of the wire, resistance of. Introduction metals are generally excellent conductors of heat and electricity because of this, we tend to neglect any resistance in wires when we examine the behavior of ordinary loads (bulbs, resistors, motors, etc) in electrical circuits.
Aim the aim of this investigation is to reveal that the factor of length affects the overall resistance so when changing the length of the conductor does resistance increase or decrease prediction i predict that as the length of the wire decreases so will the resistance. How does the length of a wire affect its resistance introduction: this first report in physics will show the investigation of how the length of a wire affects its resistance. It is proposed that there are factors that influence the extent to which metal wires carry electrical current in circuits ie the length of the wire, the cross- sectional area of the wire and the type of material in the wire.
