On wiki it says 'Near room temperature resistance of a conductor increases linearly with temperature', but I'd like to know how it varies over a wider range. A rough image I found makes it look a bit loggy or exponential or something but I can't find an equation for any given temperature.

Resistance for most metals tend to be linear with temperature over a extremely wide range:

Many metals and even some insulators become superconductive, where the resistance actually goes to zero.:
