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

If your doing physics, surely it must be in your physics text book.

Nope, it's really not.

about 16-17 nano ohm metres I think

1.678 (microohm-cm) What ever that means. Thats at room temp.

Theres a whole table about copper resistance there.

Don't know if this helps but i hope it does.

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

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

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

Cheers.

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

thats out by a factor of 10 FF

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