3 students should come to understand that the resistance of a wire depends on its length, its cross sectional area, and the material out of which it is made with some students you could go further and introduce the concept of resistivity ρ, through the relationship r = ρ l / a where r = resistance, ρ = resistivity, l = length and a = cross . An experiment to investigate the factors which affect resistance in a wire what is resistance a potential difference (v) applied across a wire of length (l), there is in the conductor, an electric field (e). Read also does length of wire affect current essay the crocodile clips and the connecting leads could have affected the fairness of the experiment they are a different type of metal from the nichrome wire and may have different properties and therefore different resistance. It does not pass trough as easily in a thin nichrome wire of an electric how does the length of wire affect its resistance the resistance of a wire depends on . Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area as resistivity is affected by temperature, we can say .
Why does the electrical resistivity of a conductor not depend on its dimensions it is found that chanfes in the length and area of cross section does not affect the resistivity of a conductor whereas it chanfes with temperaturewhy. Free essays regarding resistance wire for download 1 - 25 essay length: 2,141 words / 9 how does the length of a wire affect its resistance. The wire material is also an important factor to consider, as it can affect the wire length that can be used on a project highly conductive materials like silver and copper offer the least amount of resistance to the flow of electrons compared to a highly resistant material like rubber. Does the resistance rate depend on how much constantan wire is in the circuit essay aim the aim of this experiment is to investigate or find out how the resistance of a wire is affected by different lengths.
But the electrical resistance between two points can depend on many factors such as the conductors length, its cross-sectional area, the temperature, as well as the actual material from which it is made. Electrical resistance and conductance resistance proportional to its resistivity and length and inversely depend only on the material the wire is made of, not . Mark, the short answer is: the longer the wire, the larger the resistance more detail: resistance is a measure of how difficult it is to push electrons (the particles that carry electrical current) through a wire the larger the resistance, the more force you have to apply and. The force that acts between a pair of magnetic poles depends on why does a wire that carries electric current become hot the electric resistance in a length .
Four factors affecting resistance its value depends on four things variable resistors or potentiometers control the length of wire we introduce . How does the length of a wire affect its resistance how does the length of a wire affect its resistanceintroduction: this first report in physics will show the investigation of how the length of a wire affects its resistance. How does the thickness of a piece of wire affect its resistance what to use short pieces of nichrome wire of different thickness but same length, lamp in lamp holder, cell, switch. Resistance depends on the thickness and length of the wire used, as well as the conductor used for example, a short, thick wire made of copper will conduct electricity better than a long, thin . Procedure: in order to investigate how the resistance of nichrome wire depends on its length i will firstly have to know the formula for resistance (resistance = voltage ï¿½ current).
How does the resistance of a wire depend on its length resistance is directly prop 2 length of d wirethe electrical resistance can also be given . Factors affecting resistance temperature length of wire thickness type 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. A high resistivity means that a material does not conduct well electric charge electrical resistivity the resistance value of a wire depends on three parameters . We will write a custom essay sample on does the resistance of an electrical wire depend on its length specifically for you for only $1638 $139/page order now. 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.
How the length of a wire affects its resistance how does the length of a wire affect its resistance essay we define electrical resistance as the ratio . Extended experimental investigation: electricity in circuits ie the length of the wire, the cross- of a wire is increased then its resistance will increase . Discuss the activity to show that resistance of a conductor depends on its length and area of cross section 5 complete an electric circuit consisting of a cell, an ammeter, a nichrome wire of length l[say, marked (1)] and a plug key, as shown in fig5. An investigation into the resistance of a wire free gcse physics coursework essay a wire's resistance depends on four main factors: if you double the length .
The length of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance is the measure of how easy it is for current to flow through a wire. 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 for starters i will go through the main definitions, to get a better knowledge of what is going to happen. I is electric current measured in amps (a) the longer the length of the wire, the greater its resistance, because the longer the wire, the further the electrons have to travel.
