Answer :
Given:
The resistance of copper is R = 9.28 ohms when the temperature is T = 0 degrees Celsius.
The temperature coefficient of resistivity is
[tex]\alpha=4.3\times10^{-3}\text{ }^{\circ}C^{-1}[/tex]To find the resistance when the temperature is T' = 24.97 degrees Celsius.
Explanation:
The resistance can be calculated as
[tex]\begin{gathered} R^{\prime}=\text{ R\lparen1+}\alpha(T^{\prime}-T)\text{\rparen} \\ =9.28(1+4.3\times10^{-3}(24.97-0)) \\ =10.28\text{ }\Omega \end{gathered}[/tex]Thus, the resistance is 10.28 ohms
