A copper coil has resistance of `20.0 Omega at 0^@C` and a resistance of `26.4 Omega at 80^@C`. Find the temperature coefficient of resistance of copper.

Text Solution

AI Generated Solution

To find the temperature coefficient of resistance (α) of copper, we can use the formula for resistance at different temperatures: \[ R = R_0 (1 + \alpha T) \] Where: - \( R \) is the resistance at temperature \( T \) - \( R_0 \) is the resistance at 0°C - \( \alpha \) is the temperature coefficient of resistance ...
