Resistance\Density
5 Answers
I'm doing some coursework and I was wondering. Would there be more resistance in a wire if the wire was less dense.

For more on marking an answer as the "Best Answer", please visit our FAQ.resistance is a function of the specific resistance constant (or conductivity constant, if you like)that depends on material and temperature, the length and the cross section of the wire. density does not play a role if the material is solid (as it should be constant for constant temperature). porosity changes things a little bit, but can be accounted for by reducing the cross section accordingly. the material behaviour remains the same, though.
