In this video i will find the resistance, r=, of a piece of copper of length l=20m with a cross section area of a=05cm^2 and a given resistivity next video in this series can be seen at: https.
When we say that copper is a heavier metal than aluminium, we are comparing their densities in a similar way, when we say that copper is a better conductor than aluminium, we are comparing their resistivities density and resistivity are both bulk properties of a material their value doesn't depend on the size or shape of a particular sample – only on the material itself. Resistance of a wire – gcse physics coursework – resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by the nbsp -the resistivity of nichrome can be determined using the equation 1250 words the resistance r is the resistance wire (constantan nichrorome).

Resistivity of constantan wire coursework
Practical course: resistivity i objectives measuring the resistivity ρ for a conducting material ii choose another constantan wire with different diameter and connect the circuit shown in figure 1 2 repeat the above steps from steps a to e and fill in the blank below a. Selection of eureka wire (also known as constantan or contra) of different gauges, eg 071 mm (22 swg), 046 mm (26 swg), 032 mm (30 swg) and 024 mm (34 swg) metre rule. 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. 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 current is the rate of flow of charge through a conductor, and it is measured in amps using an ammeter - 30 swg (diameter) constantan wire - 1 metre ruler.
