Does resistance go up with temperature
WebApr 25, 2016 · For copper the temperature coefficient of resistivity is $3.9\times 10^{-3} \text{K}^{-1} $ and the temperature coefficient of thermal linear expansion is $1.6\times 10^{-4} \text{K}^{-1} $. They differ by a factor of about 24 so a change in temperature will cause a bigger change in resistance than in the linear dimensions of copper. WebDec 30, 2024 · That's because the "resistance" of a light bulb does not directly depend on the voltage: It depends on the temperature of the filament, and the temperature depends on both the voltage and time. …
