I need to know the resistvity value of copper, please people. I have two figures in front of me and I need to decide... NOW.

Don't worry I'm not just doing this for the fun of it, it's for Physics.

Cheers

Could be worth an extra mark. It is c/w.

the figure is so small a couple of extra decimal places makes little difference.

It's a bit of an improvement that figure than what I was going to use which was 1.6 x 10 -8 , so thanks.

Sorry read what you wrote as 1.678 to the minus 9, its ok

What do you think it is?

That wasn't aimed at you, I was writing that message before I saw your post, but anyway...

Cheers.

It looks like 1.678 x10 -8 is the right number. Still, I appreciate any more comments.

I told you, 16-17 x 10^-9 ohm metres

you do realise nano is to the -9 right? doing physics and all

I really need an exact figure, it should be a decimal x 10 to a negative power.
