1. ### Need help in determining a source of error in an experiment

The formula = max-min/total... I just want to know the difference between relative and total experimental error.
2. ### Need help in determining a source of error in an experiment

Homework Statement 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...
3. ### Where Should I Go From Here?

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.
4. ### Need help in determining a source of error in an experiment

Homework Statement 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...
5. ### How does corrosion affect the resistivity of copper wire?

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...
6. ### How does corrosion affect the resistivity of copper wire?

Thank you so much for answering. I didn't know the posting procedure as its my first time on here. Will remember next time..thanks
7. ### How does corrosion affect the resistivity of copper wire?

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. Thank you
