Hi I'm new to this site and would be grateful for a bit help with some home work exam to follow shortly...if I have the resistance and the csa how do I work out the length?... Thanks guys
Cross sectional area PB. I guess we talkin wire diameters. My answer would be find the equations that use these known measurements and substitute where required.What is the csa?

So to use that equation you need three of the four parameters. You apparently only have two. You also need to know the resistivity. Doesn't it make sense that the length of aluminum wire is going to different than length of copper or the length of steel?Cross sectional area PB. I guess we talkin wire diameters.

R=(resistivity x length) / csa
Treeman was being helpful as much as he could. I assumed there was more info to reveal - this seems to be the case often.So to use that equation you need three of the four parameters.

@Hotfingers : Do you have either the resistivity or at least the material that the wire is made out of?
No problem there. I didn't realize until after I had posted that the two quotes in my response were from different people, so I went back and added the note to the TS.Treeman was being helpful as much as he could. I assumed there was more info to reveal - this seems to be the case often.
