# Problem: true or false: most conducting materials have different resistances at different temperatures.

###### FREE Expert Solution

The dependence of resistance on temperature is given by:

$\overline{){\mathbf{R}}{\mathbf{=}}{{\mathbf{R}}}_{{\mathbf{0}}}{\mathbf{\left(}}{\mathbf{1}}{\mathbf{+}}{\mathbf{\alpha }}{\mathbf{∆}}{\mathbf{T}}{\mathbf{\right)}}}$
