Factors affecting resistance wire
Variables affecting electrical resistance the total length of the wires will affect the amount of resistance the longer the wire, the more resistance that there. Class practical a simple investigation of the factors affecting the resistance of a wire. Factors affecting resistance mr baker factors affecting the resistance resistance of a wire. Length of the wire resistance is directly proportional to the length of the wire more the length of the wire, longer is the distance to be covered by the electrons. To investigate the factors of affecting the resistance of a wire ohm's law aim: to investigate the factors of affecting the resistance of a wire voltage is the electrical force, or pressure, that causes current to flow in a circuit voltmeter's range until i reach 80cm, and take readings each time. What's the factors affecting resistance of a wire and why thank you. 9 rows learn about the physics of resistance in a wire change its resistivity.
I shall look at various factors which can affect the resistance of a wire and investigate one of these in greater detail i shall start off with theory on resistance and use it to make a prediction and then plan and carry out an experiment to obtain enough evidence to prove or disprove my prediction. Factors affecting the resistance of wire 1883 words | 8 pages aim: to investigate the factors that affect the resistance in a conductor the main factors that affect the resistance in a conductor are: length temperature cross sectional area material magnetism the factor that we are going to change is the cross sectional area. Thanks for a2a there is a famous formula it depends on 4 factors 1 length 2 area of cross section 3 resistivity-can be changed by changing material 4 temperature explanation: when you consider one material for wire resistivity is fixed,beca. The diameter of the wire will have an affect on the resistance of a wire this is because the electrons have to squeeze together more to pass through a thin wire than they do to pass through a thick wire i can predict that the. I am going to investigate what factors affect the resistance of a wire there are three main factors which affect the resistance of a wire. Thickness (diameter, circumference, radius or area) of wire: the cross sectional area of a piece of wire greatly affects the resistance if the wire is very thick it will allow a high current through because there is more room for more electrons to transfer the current.
An investigation into the resistance of resistance depends on four main factors: how manipulating these variables affect the resistance of the wire. Variables affecting electrical resistance 1 the total length of the wires will affect the amount of resistance 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. Essay about factors affecting the resistance of a wire - factors affecting the resistance of a wire the aim of this experiment is to investigate one factor that affect the resistance of a wire i will do this by performing an experiment. Factors affecting resistance 1 factors affecting resistancereported by: ralph lery guerrero kevin roxas marco lauro delos santos 2 resistance• is defined as an obstacle to the flow of electric current• is the opposition offered by any object to the passage of an electric current through it 3.
The resistance of a typical conducting wire is low when temperature is how does temperature affect the resistance of a factors affecting resistance in a wire. Length, cross-sectional area, kind of material, resistivity and temperature: the ir re latio nships factors affectingfactors affecting resistanceresistance.

Factors affecting resistance wire
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 currents are measured. 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. The resistance of a wire, or any conductive object whose shape can be defined by a length parallel to conduction and an area normal to conduction, is defined by.
There are several factors that affect the resistance of a conductor material eg copper has lower resistance than steel length - longer wires have greater resistance thickness - smaller diameter wires have greater resistance temperature. Factors affecting the resistance of a wire research paperfactors affecting the 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. Si unit of resistance is ohm, ω resistivity is ohm meter, ω m and that of current is ampere, a factors affecting resistance are: length of the conductor (l), area of cross-section of the conductor (a) r α l and r α 1/a factors affecting resistivity are: material of the conductor, temperature at which the conductor is used. First, the total length of the wires will effect the amount of resistance 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. Table 3 (varying length) - swg 28 material swg thickness (diameter in g) length (cm) reading no current (a) average (a) resistance ( ) constantan table 4.
Electrical currents are routinely harnessed and transmitted via interconnected wires the purpose of this research is to identify factors commonly responsible for affecting the resistance of current, or flow of electricity, across a wire in an electrical circuit. • precision wirewound resistors consist of resistance wire • various and complex factors contribute to the instability of. Resistance is a property four factors affecting resistance variable resistors or potentiometers control the length of wire we introduce into. Temperature: (an increase in temperature will increase the resistance) cross sectional area: (the larger the wire, the less resistance) the length of the wire: (the longer the wire, the more resistance)the material of the wire: (some materials are better conductors than others, and this causes less resistance.
