## Homework Statement

I'm supposed to estimate at what temp. copper will have the same resistivity as tungsten at 20 deg. C.

## Homework Equations

The only equation I think is relevant is

p=p0[1+alpha(T-T0)]

## The Attempt at a Solution

I know the resistivity of both copper and tungsten at 20 degrees C. I just don't know what I should do about the resistivity, p0, at temperature, T0 since I don't know either of those quantities.

I cant cancel those variables out when I set p(tungsten)=p(copper) so I'm not sure what to do.
