holtadit:
I am doing a small project for physics this year on the variation of current with voltage of a metallic conductor.

Now all i want to know is the following:

How to calculate the current flowing through a 0.1m long wire of Silver which has a cross sectional area of 0.001 m2. Hence what is the resistance.

The same as above for Gold, Copper, Lead and Aluminium.

Please include the answers with relevant equations. Im doing IGCSEs by the way.

wassup:
I don't think u can calculate this because u need resistivity for this, then only u can find the resistance n then d current.
The first formula will be R=pl/A (Resistivity*Length/Area), then I=V/R. But u don't know the resistivity(p).

holtadit:
http://en.wikipedia.org/wiki/Resistivity
 here is the required resistivity values u need. Plz help me!!!!!

astarmathsandphysics:
I will answer when i get home

holtadit:
By the way astar when i used the formulas given i got the following answer for current 15094339.62 amps. It looks wrong... so whats your advice ??

Please do include the units for each value.
