I have obtained a relative error from the absolute error using the formula and received an answer of 5% while my total experimental error ((result-theory)/theory) was nearly 20%.
I have a rough idea of what they both represent but can someone please explain these two to me...
Just be passionate for what you do.. Im sure the government are looking for people just like you.
Btw, im not talking about working for a local council as a civil engineer... Im talking about being picked by the CIA to work out strategic plans etc. They are always in need of people like you.
It is known that the theoretical resistivity of copper is approximately: 2*10^-8 Ωm. But after I conducted an experiment to find the resistivity of copper, the results turned out to be: 1.68*10^-8Ωm.
This is a very small error that can be easily dismissed due to "human...
I don't think the uncovered materiel in the copper wire will differ in the resistivity factor but the overall resistivity might change since the resistance is inversely proportional to the cross sectional area of the wire and the resistance of the wire will increase as the area decreases.But...
I'm not sure if corrosion does have a significant effect on copper in general but if it does, how and why does it happen, and the process of it happening and its effect on the overall resistivity?
This is for a physics assignment...Please help if you can.
