Experiment to Determine the Resistivity of a Wire

[yeah20112012]

Here is a detailed description of my question:

Any help would be greatly appreciated.

P.S. Diameter of the wire = 0.425mm +/- 0.005mm .

Look for that formula in your book.

 

[yeah20112012]

Do you mean Resistance = ((p x Length) / Area), where p is the Resistivity? If so, that was not my question!

Yeha that looks right.

EDIT: Wait, something is wrong (not the formula)...

EDIT2: never mind, I was right. Find the cross sectional area of the wire.

Area = 0.04515625 x pi . How is this relevant to the graph?!

for learning to graph with excel just google "how to plot a graph in excel"
google is very powerful search engine. learn to use it for your end. if you learn how to
use google (there are lot of different ways you can do search) most of the questions
you get in physics will be easier in the sense that , with right keywords , solutions are easily available. or you can go to the right forums...

Am i overlooking something here? What are you graphing? what is your graph?
