coolnufc said:Hi guys, I am trying to work out ρ in an experiment.
Ive got down to ρ/AxV = 6.4
I know V = 2 and A=0.0907mm, but it should be m.
If i then work it out i get a stupidly small answer. Anyone help me out. Its like 0.0016096
Resistivity is a measure of a material's ability to resist the flow of electric current. It is different from resistance in that resistance depends on the size and shape of the material, while resistivity is an intrinsic property of the material itself.
In coursework, resistivity is determined by measuring the resistance of a material and using its dimensions to calculate the resistivity value. This is typically done by using a multimeter to measure the resistance and a ruler to measure the length and cross-sectional area of the material.
The resistivity of a material can be affected by factors such as temperature, impurities, and the type of material. For example, as the temperature of a material increases, its resistivity also increases. Additionally, materials with higher impurity levels tend to have higher resistivity values.
Resistivity and conductivity are inversely related. This means that as the resistivity of a material increases, its conductivity decreases. Conductivity is the inverse of resistivity and is a measure of how easily a material can conduct electric current.
Resistivity is an important property that is used in a variety of real-world applications, such as in the design of electrical circuits, determining the quality of materials used in construction, and in the development of electronic devices. It is also used in geophysical surveys to map the subsurface and locate natural resources such as minerals and oil.
