Question:medium
At what temperature will the resistance of a copper wire become three times its value at 0°C? (Temperature coefficient of resistance for copper \( \alpha = 4 \times 10^{-3} /°C \))
At what temperature will the resistance of a copper wire become three times its value at 0°C? (Temperature coefficient of resistance for copper \( \alpha = 4 \times 10^{-3} /°C \))
Show Hint
The resistance of a conductor increases linearly with temperature when the temperature coefficient of resistance is constant.
