Question

A wire with a resistance of 6.0Ω is drawn out through a die so that its new length is threetimes its original length. Find the resistance of the longer wire, assuming that the resistivity and density of the material are not changed during the drawing process.

Answer 1

@ganeshie8, your ideas pls

Answer 2

basically you stretched that wire so that, its length becomes 3 times

Answer 3

any idea how the new "cross sectional area" wud change ?

Answer 4

would change by 3^2

Answer 5

I got it, thanks alot.

Answer 6

Didn't think about that. Was just doing the length thing alone. Thanks @ganeshie8
